  A.  x² -4

  B.  2x² +8

Step-by-step explanation:

The area of the larger square is the square of its side length, so is x².

A. The area of each of the smaller squares is 1² = 1. There are 4 of them, so their total area is 4×1 = 4. The shaded area is that much less than the area of the larger square, so is ...

  x² - 4

__

B. The smaller squares have side length 2, so their area is 2² = 4. There are two of them, so the total area of the smaller squares is 2×4 = 8.

The two large squares have a total area of ...

  2 · x² = 2x²

So, the total shaded area is ...

  2x² + 8

its 8
