Answer:

16x^2 - 16x + 4

Step-by-step explanation:

Area (a) = width (w) times length (l)

Because the length and width of a square are the same, the area will be (4x-2) * (4x-2)

You can use FOIL to solve this.

First: 16x^2

Outside: -8x

Inside: -8x

Last: 4

So that's 16x^2) - 8x - 8x + 4.

Combine like terms to get your final answer:

16x^2 - 16x + 4
