Factoring Trinomials

Factor
n² + 16n + 63

• (n-7)(n+4)
• (n+7)(n-9)
• (n-3)(n-10)
• (n+7)(n+9)

Factor
x² - 5x - 36

• (x - 4)(x + 9)
• (x - 6)(x + 6)
• (x + 4)(x - 9)
• (x -12)(x + 3)

Factor
3v² - 4v - 7

• (3v-7)(v+1)
• 3(v-7)(v-1)
• (3v+1)(v-9)
• (3v+1)(v-10)

Solve
x² + 2x - 24 = 0

• x = -6, x = 4
• x = 6, x = -4
• x = 12, x = -2
• x = 8, x = -3

Solve for the values of x:

(2x - 1)(x + 4) = 0

• x=1/2, x= -4

• x=1/2, x= 4

• x= 1, x=-4

• x=-2.5, x=4

Solve:

3x² + 17x + 10 = 0

• x = 2/3, x = 5

• x = -2/3, x = -5

• x = 5/3, x = 2

• x = -5/3, x = -2

Factor $4x^{2\ }+\ 12x\ +\ 9$ 
(Hint: Is this a Perfect Square Trinomial?)

•  $\left(2x\ -3\right)^2$  

•  $\left(2x\ +3\right)^2$  

•  $\left(2x\ -3\right)\left(2x\ +\ 3\right)$  

• Cannot be SOLVED

Factor the difference of squares:

25x²-81

• (5x-9)²

• (5x+9)(5x-9)

• 25(x-9)²

• (9x+5)(9x-5)
