​lets study more of these examples i know this is a different type of math
say we have xn and we want to express something right heres something to express we know we let n be a power base on x so we know when
n=0 its horizontic, n=9 its nonic,
n=1 its linearic, n=10 its decic, and so on but what if we deal with higher order sa
n=2 its squaric, n=20 its vigintic, n=90 its nonagintic,
n=3 its cubic, n=30 its trigintic, n=100 its centic,
n=4 its quartic, n=40 its quadragintic, what if n=97 we can rewrite it as x97 since n is
n=5 its quintic, n=50 its quinquagintic, x power we will write since it at 90s place
n=6 its sestic, n=60 its sesagintic, we will add nonagintic when we subtract that
n=7 its septic, n=70 its septuagintic, number by 90 so 97-90=7 since we get 7
n=8 its octic, n=80 its octuagintic, we get septic we remove tic on the side move it on the left we get sepnonagintic i want you to try the rest of these excerises on your own and see how far you get good luck

​lets classify some polynomials f(x)=5x5+9x4+20x3+37x2+74x+74 we can find the leading coefficient from this sestinomial for o=the leading coefficient we must look for the degree which in that case is x5 we see 5 proof f(x)=5x5+9x4+20x3+37x2+74x+74 is been multiplied so we can conclude our leading coefficient is 5 to find the constant we must look for something that does not have the variable respected to if f(x)=x no constant but if its different variable then it is an constant we can proove it f(x)=5x5+9x4+20x3+37x2+74x+74 we can see 74 is the constant so our constant is 74, now that is it with today lecture now i want you to try the rest of these excersizes on your own and see how far you get.

​lets try one example multiplying monomials say i get 6x5(5x4) first we multiply the constant then do product rule 6x5(5x4)=30x5(x4)=30x5+4=30x9 lets try the last one this time dealing with roots 53√x5(6*5√x2+4*11√x10-7*5√x6) well first thing first is to seperate them so we get 53√x5(6*5√x2+4*11√x10-7*5√x6)=53√x5(6*5√x2)
+53√x5(4*11√x10)+53√x5(-7*5√x6)=303√x5*5√x2+203√x5*11√x10-353√x5*5√x6
convert roots to exponitional fractions 303√x5*5√x2+203√x5*11√x10-353√x5*5√x6
=30x5/3x2/5+20x5/3x10/11-35x5/3x6/5 then use product rule 30x5/3x2/5+20x5/3x10/11
-35x5/3x6/5=30x5/3+2/5+20x5/3+10/11-35x5/3+6/5 then do add both fractions 3 of them 5/3+2/5=25/15+6/15=31/15 5/3+10/11=55/33+30/33=85/33 5/3+6/5
=25/15+18/15=43/15 so 30x5/3+2/5+20x5/3+10/11-35x5/3+6/5=30x31/15+20x85/33-35x43/15 now convert them back to root 30x31/15+20x85/33-35x43/15
=30(15√x31)+20(33√x85)-35(15√x43) now i want you to try the rest of these excerises on your own good luck.

(x+2)/3 since the denominator is the same we put them together lets try another one this time dealing with trinomial (3x3+9x2+9x+7)/(3x) first we have to seperate the coefficients we get (3x3+9x2+9x+7)/(3x)=3x3/(3x)+9x2/(3x)+9x/(3x)+7/(3x) then simplify the coefficients we get 3x3/(3x)+9x2/(3x)+9x/(3x)+7/(3x)=x3/x+3x2/x+3x/x+7/(3x) then we divide the x we get x3/x+3x2/x+3x/x+7/(3x)=x3/x1+3x2/x1+3x1/x1+7/(3x1)=x3x-1+3x2x-1+3x1x-1+7x-1/3
=x3-1+3x2-1+3x1-1+7x-1/3=x2+3x+3x0+7/(3x)=x2+3x+3+7/(3x) lets try the last one now i want you to try the rest of the excersizes on your own and see how far you get

​lets say i got a trinomial divided by binomial example (x2+438x+437)/(x+1) now lets work this one together we seperate the numberator which will look something like this first off we divide x2 by the highest degree of denominator on x x2/x=x now we can use that x and multiply the numerator we get x(x+1)=x2+x now we can subtract the numerator by x2+x we get (x2+438x+437-x2-x)/(x+1)=(437x+437)/(x+1) save the x for later for now lets divide 437x by x so 437x/x=437 then mutliply it by x+1 437(x+1)=437x+437 we can subtract again (437x+437-437x-437)/(x+1)=0/x+1
now we add those parts together x and 437 we get x+437 so in conclusion (x2+438x+437)/(x+1)=x+437 now i want you to try the rest of the problems on your own and see how for you get.

​lets say i want to factor 50x4+20x3+10x2 so what we can do is to find the lowest term in this equation which is x2 so we separate it we get 50x4+20x3+10x2
=x2(50x2+20x+10) now find the lowest coefficient and see if others are factorable if not reduce it until you get the exact one x2(50x2+20x+10)=x2(10*5x2+10*2x+10*1)
=
10x2(5x2+2x+1) lets try another one 15x20+6x8+30x18+21x2+54x16+18x4+9x12 so what we can do is to again find the lowest term which is x2 once again so 15x20+6x8+30x18
+21x2+54x16+18x4+9x12=x2(15x18+6x6+30x16+21+54x14+18x2+9x10) now find the lowest coefficient which is 6 lets see if all is the factor of 6 x2(15x18+6x6+30x16+21+54x14+18x2
+9x10) sems like 15 21 and 9 is not the factor of 6 so we 6/2 3 much better now we can move 3 on left side we get x2(15x18+6x6+30x16+21+54x14+18x2+9x10)=3x2(5x18+2x6
+10x16+7+18x14+6x2+3x10) lets arrange it from from highest degree to lowest degree we get 3x2(5x18+2x6+10x16+7+18x14+6x2+3x10)=3x2(5x18+10x16+18x14+3x10+2x6+6x2+7)

​lets i got d2+5d+6=0 and we want to find the quadratic formula well for ax2+bx+c=0 we use x=-(b±√(b2-4ac))/2a so lets plug those values in d2+5d+6=0 => 1*d2+5d+6=0 a=1, b=5, c=6 now lets plug that into formula x=-(b±√(b2-4ac))/2a=-(5±√(52-4*1*6))/(2*1)=-(5±√(25-24))/2=-(5±√1)/2=-(5±1)/2 so now lets separate x=-(5+1)/2=-6/2=-3 and x=-(5-1)/2=-4/2=-2 for u=-(b+√(b2-4ac))/2a, and
v=-(b-√(b2-4ac))/2a lets say I want to factor it well we use the formula for ax2+bx+c
a(x-u)(x-v) if there is something that is not whole all we can do for example u is not whole all we get is a(x-u)(x-v)=(ax-au)(x-v) let's try that let u=-2, v=-3 we can plug those in (d-(-2))(d-(-3))=(d+2)(d+3) so, in conclusion, d2+5d+6=(d+2)(d+3) now I want you to try the rest of the problems on your own and see how far you get.

​say i got an equation 5x2+2x+1 and i want to convert that into into vertex form from ax2+bx+c to a(x-h)2+k well lets use a b c and see if we figure it out so first tking first is to seperate c into n+k where c=n+k we get ax2+bx+c=ax2+bx+n+k then factor a b and n by a we get ax2+bx+n+k=a(x2+bx/a+n/a)+k lets solve for h using vertex formula a(x-h)2+k first expand the equation we get a(x-h)2+k=a(x-h)(x-h)+k=a(x2-2xh+h2)+k now set that equal to a(x2+bx/a+n/a)+k we get a(x2-2xh+h2)+k=a(x2+bx/a+n/a)+k we can cancel the terms as highlighed here a(x2-2xh+h2)+k=a(x2+bx/a+n/a)+k => -2xh+h2=bx/a+n/a we can group these in 1st term we get -2xh=bx/a and 0th term we get h2=n/a lets try solving for h tht has only a, b, and c, on 0th term h2=n/a h=√(n/a) oh no theres an n how we gonna solve it any how lets try 1st term -2xh=bx/a solve for h we get h=-b/(2a) thats good now we can solve for n where n/a=h2 plug h=-b/(2a) in we get n/a=(-b/(2a))2=b2/(4a2) then solve for n we get n=b2/(4a) plug that into c=n+k we get c=b2/(4a)+k now solve for k we get from c=b2/(4a)+k to k=c-b2/(4a) now we got h=-b/(2a) and k=c-b2/(4a) we can plug them into vertex formula a(x-h)2+k=a(x-(-b/(2a)))2+c-b2/(4a)
=
a(x+b/(2a))2+c-b2/(4a) now we got a new formula a(x+b/(2a))2+c-b2/(4a) now we can just plug them in we always need to remember and test this formula if it works or not lets plug 5x2+2x+1 into vertex formula we have a=5, b=2, c=1 since it is ax2+bx+c lets use the vertex formula to plug the values in a(x+b/(2a))2+c-b2/(4a)
=5(x+2/(2*5))2+1-22/(4*5)=5(x+1/5)2+1-4/(4*5)=5(x+1/5)2+1-1/5=5(x+1/5)2+4/5 take any trinomial that has a highest degree of 2 and see if it works and it actually works make sure to double check as i encourage you to do so try the excersizes on your own and see how far you get good luck.

​say i got the vertex equation 5(x+3)2+10 and we want to find the minimum value of a function for to do that is to use the axis of symmetry which is x=-b/(2a) we can use 2 vertex's and set them equal we get a(x-h)2+k=a(x+b/(2a))2+c-b2/(4a) we know h=-b/(2a) we can plug the values in a=5 -h=3 k=10 right now -h is what we need so lets solve for h we get h=-3 lets plug h into x we get 5(x+3)2+10=5(-3+3)2+10=5(0)2+10=10 we get our minimum value or another way to do that is to let x=h a(x-h)2+k=a(h-h)2+k=a(0)2+k=k this is how you manipulate minimum value of y axis or other words range since the parabola is continious in y axis above k we get k<y<∞ when a>0, if a=0 then y=k, if a<0 then -∞<y<k for all conditions x has all numbers which means -∞<x<∞ you may not see it but it continius on and on and on as you keep going it doesnt stop which means any parabolas is always continious if you have a standard quadratic form use this k=c-b2/a do not use c only use the k formula good luck

​if i have a equation 6(x-7)2+42 and i want to convert it into a standard quadratic form lets create the formula for it so let a(x-h)2+k=ax2+bx+c lets solve for the left hand side a(x-h)2+k=ax2+bx+c => a(x-h)(x-h)+k=ax2+bx+c =>
a(x2-2xh+h2)+k=ax2+bx+c => ax2-2xah+ah2+k=ax2+bx+c lets use

ax2-2xah+ah2+k=6x2-2x*6*7+6*72+42=6x2-84x+294+42=6x2-84x+336 lets try another one 5(x-2)2-15 let 5(x-2)2-15=a(x-h)2+k so a=5 h=2, and k=-15 now use a formula

=a(x-2)2-5 now we have to solve for a using a pt that is not a vertex like we did so x=10, y=-1 so let y=a(x-2)2-5 -1=a(10-2)2-5 4=a(8)2 4=64a a=1/16 lets plug a in we get a(x-2)2-5=(x-2)2/16-5 now i want you yo try the rest of the excerises on your own and see how far you get.

say i got the standard quadratic form 5x2+2x+10 and to find the 0 within what x value we need we'll just create a formula out of ax2+bx+c lets solve for x ax2+bx+c=0 let c=n+k we know k=c-b2/(4a) so c=n+c-b2/(4a) solve for n n=b2/(4a) we get c=n+k=b2/(4a)+c-b2/(4a) i know its unfactored but bear with me as we go along so ax2+bx+c=ax2+bx+b2/(4a)+c-b2/(4a)=a(x2+bx/a+b2/(4a2))+c-b2/(4a) lets use the vertex formula to solve a ploblem a(x-h)2+k=a(x2+bx/a+b2/(4a2))+c-b2/(4a)=> a(x2-2xh+h2)+k=a(x2+bx/a+b2/(4a2))+c-b2/(4a) use k=c-b2/(4a) if you havent remember it i encourage you to rewind to find the solution lets continiue a(x2-2xh+h2)+c-b2/(4a)=a(x2+bx/a+b2/(4a2))+c-b2/(4a) cancel stuff accept x2 we get a(x2-2xh+h2)+c-b2/(4a)
=a(x2+bx/a+b2/(4a2))+c-b2/(4a) => x2-2xh+h2=x2+bx/a+b2/(4a2) we know h=-b/(2a) we can plug those values in on the left we get x2-2xh+h2=x2-2x(-b/(2a))+(-b/(2a))2=x2+bx/a+b2/(4a2))
now check x2+bx/a+b2/(4a2)=x2+bx/a+b2/(4a2) seems perfect to factor lets factor this squaric trinomial x2+bx/a+b2/(4a2)=(x+b/(2a))2 now we can set variable in we get a(x2+bx/a+b2/(4a2))+c-b2/(4a)=a(x+b/(2a))2+c-b2/(4a) now solve for 0 a(x+b/(2a))2+c-b2/(4a)=0 => a(x+b/(2a))2=b2/(4a)-c => (x+b/(2a))2=b2/(4a2)-c/a => x+b/(2a)=±√(b2/(4a2)-c/a) set a into perfect square 4a2 on c we get x+b/(2a)=±√(b2/(4a2)-c/a=x+b/(2a)=±√(b2/(4a2)-4ac/(4a2))=x=-b/(2a)±√((b2-4ac)/(4a2))=
-b/(2a)±√(b2-4ac)/(2a)=(-b±√(b2-4ac))/(2a) now with our quadratic formula we solved for we can finally plug the values in so for 5x2+2x+10=0 set a=5, b=2, c=10 then x=(-b±√(b2-4ac))/(2a)=(-2±√(22-4*5*10))/(2*5)
=(-2±√(4-200))/10=(-2±√(-196))/10 since the root part is <0 there is no solution but good luck on the next page.

​say i got an equation 3(x-5)2-7 and i want to find when our equation going to be 0 within x so we setup our vertex equation a(x-h)2+k and set that equal to 0 a(x-h)2+k=0 now solve for x a(x-h)2+k=0 => a(x-h)2=-k => (x-h)2=-k/a => x-h=±√(-k/a) x=h±√(-k/a) now we solve for x now plug the values in we get a=3 h=5, and k=-7 now plug them into formula x=5±√(7/3) now we can seperate x1=5+√(7/3), and x2=5-√(7/3) seems straight forward lets try another another one 7(x-3)2-6 lets use the formula to find the 0 x=h±√(-k/a)=3±√(6/7) lets seperate them x1=3+√(6/7),
x2=3-√(6/7) lets try a another one 6(x+4)2+44 lets use the formula x=h±√(-k/a) so a=6 ,h=-4, and k=44 x=-4±√(-44/6)=-4±√(-22/3) oh no this seems like there is no solution to the equation so answer is no solution since we have negative root remember if negative root do not count as an solution so i want you to try the rest of the ploblem on your own and see how far you get.

​lets say i got an equation 7x2+5x+8 and i want to find the discriminant of it but first lets explain how discriminant works well discriminant is the test if the root has a positve or negative value if its positive then it will return a real number if its negative it will return an imaginary root which is ALWAYS REMEMBER i=√-1 which cannot be an solution lets find the discriminant out of the quadratic formula x=(-b±√(b2-4ac))/2a we can see the root part we can set that to d=b2-4ac so if d>0 then it has 2 solution when d=0 then it has 1 solution and when d<0 then it has no solution got it lets use it to solve the discriminant so we do have the equation 7x2+5x+8 we can plug them in we get a=7, b=5, and c=8 lets plug them in d=b2-4ac => d=52-4*7*8=25-224=-199 so this one has no solution lets try another one 8x2+8x-4 like always use discriminant d=b2-4ac=82-4*8*-4=64+128=192 seems like it has 2 solutions now i want you to try the rest of the excerises on your own and see how far you get

​say i got an equation o2-7o+10 and we want to factor such an equation one way to do it is to use quadratic formula x=(-b±√(b2-4ac))/(2a) note also focus on the discriminant in bolded one any how o=(-(-7)±√((-7)2-4*1*10)/(2*1)=(7±√(49-40))/2
=(7±√(49-40))/2=(7±√(9))/2 note discriminant>0 since our discriminant=9 so there are 2 solution if you check the discriminant so we use (x-x1)(x-x2) lets continiue factoring (7±√(9))/2=(7±3)/2 then we setup the solution o1=(7+3)/2=10/2=5, o2=(7-3)/2=4/2=2 lets plug them in this time using o we get (o-5)(o-2) so in factored conclusion o2-7o+10=(o-5)(o-2) lets try he last one s2-8s+16 to factor this squaric trinomal as always use the quadratic formula also use the discriminant method for this one x=(-b±√(b2-4ac))/(2a) s=(-(-8)±√((-8)2-4*1*16))/(2*1)
=(8±√(64-64))/2=(8±√0)/2 note we have a discriminant=0 so there is one solution we rewrite as (x-x1)2 lets continue solving (8±√0)/2=8/2=4 so s1=4 so we get (s-4)2 so in factored conclusion s2-8s+16=(s-4)2 now i want you to try the excersies on your own and see how far you get

=(22±√(484+1,280))/80=(22±√1,764)/80 since our discriminant>0 we will use (x-x1)(x-x2) h=(22±√1,764)/80=(22±42)/80=(11±21)/40, h1=(11+21)/40=32/40=4/5, and h2=(11-21)/40=-10/40=-1/4 lets plug those values in we get (h-4/5)(h+1/4) since we got fractions we must seperate them we get (h-4/5)(h+1/4) => since leading coefficient a=40 we get 40(h-4/5)(h+1/4) remove all denominators we get 40(h-4/5)(h+1/4)=2(h-4)(h+1)

say we have xn and we want to express something right heres something to express we know we let n be a power base on x so we know when
n=0 its horizontic, n=-9 its andtionic,
n=-1 its antilinearic, n=-10 its antidecic, and so on but what if we deal with higher order
n=-2 its antisquaric, n=-20 its antivigintic, n=-90 its antinonagintic,
n=-3 its anticubic, n=-30 its antitrigintic, n=-100 its anticentic,
n=-4 its antiquartic, n=-40 its antiquadragintic, say i got power n=-47 and we want
n=-5 its antiquintic, n=-50 its antiquinquagintic, to classify the power it is on so our
n=-6 its antisestic, n=-60 its antisesagintic, tens is 4 which is antiquadragintic
n=-7 its antiseptic, n=-70 its antiseptuagintic, and ones is 7 which is antiseptic so
n=-8 its antioctic, n=-80 its antioctuagintic, putting them together we get antiseptenquadragintic anti means opposite if you use 2 then it is not opposite so i want you to try the rest of the excerises on your own and see how far you get
