Question 157459
Multiply (-2x+2)^2

My result is -2x^2-4x+4

Is it correct?

Nice try but the answer is not right.

(-2x+2)^2 = (-2x + 2)(-2x + 2)

Let's use FOIL.

-2x times -2x = 4x^2

-2x times 2 = -4x

2 times -2x = -4x

2 times 2 = 4

We now put it terms together.

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

We now combine like terms and the final answer is:

4x^2 - 8x + 4
