• (x + 6)(x - 8)

• (x + 12)(x - 4)

• (x -16)(x - 3)

Factor k²+7k+10

• (k+2)(k+5)

• (k-2)(k-5)

• (k+10)(k+4)

*hint: what is the middle term's value if there is no coefficient of x?

• (x + 9)(x - 4)

• (x - 6)(x - 6)

• (x - 9)(x + 4)

What is the Greatest Common Factor of the following polynomial?
12t³ + 30t² + 48t

• 12t

• 6t³

• 6t

• 12t³

Find the greatest common factor of
6x⁴y³ - 12x⁴y² + 6x³y²

• 6

• 6xy

• 6x³y²

• 6x⁹y⁶

What is the GCF of the polynomial
24x⁹ - 36x⁶ + 60x³?

• 6x

• 6x³

• 24x⁹

• 24x

Which of the following is a good definition for the Greatest Common Factor of a polynomial?

• The constants and variables that are the smallest

• The constants and variables that are the largest

• The largest combination of constants and variables you can "pull out" of a polynomial

• The common factor that is the greatest

Why do we need to find the GCF of polynomials? Choose the BEST option.

• Because Ms. Cooper and Ms. Glefke said so

• To simplify the polynomials as much as possible before working with them

• To get rid of stuff

• Because the GCF makes the problem impossible to solve
