Factor A=1 Zero

In the equation
 (x + 2)(x - 3) = 0, the binomials are called...?

• Factors

• Products

• Multiples

• Zeros

What is the first step in solving 
(x + 2)(x - 3) = 0      ?

• Plug in zero for x

• Solve for x

• FOIL

• Set each binomial factor equal to zero

Solve for the values of x:
(x + 2)(x - 3) = 0

• { 2, 3 }

• { -2, -3 }

• { 2, 3 }

• { -2, 3 }

Solve for the values of x:
(2x - 1)(x + 4) = 0

• { 1/2, -4 }

• { 1/2, 4 }

• { 2, -4 }

• { -2, 4 }

If a polynomial has 2 factors, it will have 2 zeros (or 1 zero with a multiplicity of 2).

• True

• False

To find zeroes of polynomials, we...

• say x=0

• make pancakes

• ask NASA

• set factors equal to zero

Write the factors of the polynomial from the zeros in the graph. Remember to look at your roots, multiplicity, and end behavior!! Use your notes!

• (x - 3) (x + 2) (x + 5)

• (x - 5) (x - 2) (x + 3)

• (x + 3) (x + 2) (x + 5)

• (x - 3) (x - 2) (x - 5)

Write the factors of the polynomial from the zeros in the graph. Remember to look at your roots, multiplicity, and end behavior!! Use your notes!

• (x - 3) (x + 2) (x + 5)

• (x - 5) (x - 2) (x + 3)

• (x + 3) (x + 2) (x + 5)

• (x - 3) (x - 2) (x - 5)

Solve and find your x-intercepts:
0=x(x - 6)

• x=0 and x=-6

• x=1 and x=-6

• x=0 and x=6

• x=6

Solve and find your zeros:
z(z - 15)=0

• z=0 and z=15

• z=0 and z=-15

• z=-15

• z=15
