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
