Answer:
4x^2 - 16x + 16
Step-by-step explanation:
So first you have to know the formula:
If the expression is (x + y)^2 you would have x^2 + 2xy + y^2
So now you have (2x - 4)^2
2x^2 = 4x^2
2(2x)(-4) = -16x
-4^2 = 16
Add them together:
4x^2 - 16x + 16
Answer:
Wouldn't be 4x^2 - 16x + 16 if not please correct me!! :) it took me a long time to solve this! I kept on having to redo it! So I am not 100% sure this is right!
