Question

Factor completely.
128-32x + 2x² =

Answer 1

(x - 8)(x + 8) will be your answer.

Explanation:

Lets do this step by step.

1) Find the GCF of the expression.

2x^2 - 32x - 128 --> 2(x^2 - 16x - 64)

2) Use the X-method to factor.

It gives us the expression 2(x^2 - 8x)(-8x -64).

3) Factor for x.

(x^2 - 8x) --> x(x - 8)

(-8x - 64) --> -8(x + 8)

Our answer is (x - 8)(x + 8)

Answer 2

`\mathrm {(x - 8)(x + 8)}`

had to be corrected. sorry for the inconvenience.
