Factoring and Polynomial Unit Review

Find the product:
(5n-8)(5n+8)

• 25n²-64

• 10n²

• 5n²+16

• 16

Factor
18a²b⁴c + 24ab³c²

• 6ab³c(3ab + 4c)

• 3abc(6ab³ + 8b²c)

• 6abc(3ab³ + 4c)

• 6ab3c(3b + 4c)

Factor the polynomial. 
x²-4x-32

• (x-8)(x+4)

• (x-4)(x-32)

• (x+3)(x-4)

• x+2)(x+5)

• -6c⁵
• -6c
• 6c
• -6c⁶

Match each polynomial to its factored form:

• (x-4)(x-1)

• (x+4)(x-1)

• (x+4)(x+1)

• (x-4)(x+1)

The GCF of 2x²-4x+8 is (a)   .

• 2x

• 2

• x

• 1

If a = 4x and b = 5, write a SUM of Cubes Problem that would need to then be factored.
