Question

Use the GCF of the terms to write the expression as the product of two factors with integer coefficients.

-2x3 - 4x2 + 4x
A. x(-2x2 - 4x + 4)

B. -2x(x2 + 2x - 2)

C. x(-2x2 + 2x - 2)

D. -2x(-2x2 + 2x - 2)

Answer 1

-2x^3 - 4x^2 + 4x

-2x^3 = -2x(x^2)

-4x^2 = -2x(2x)

4x = -2x(-2)

so GCF= -2x

-2x3 - 4x2 + 4x = -2x(x^2 + 2x - 2)

answer is B. -2x(x^2 + 2x - 2)
