You can put this solution on YOUR website!
you are given: the diameter of a circle is %28x%2B2%29 units
you need to express the area of the square in the figure as a polynomial
as you know, the area of the square is A=a%5E2 where a is the side of the square
if you take a close look at your picture, you will see that a=%28x%2B2%29 units
so,the area of the square will be:
A=a%5E2units%5E2
A=%28x%2B2%29%5E2units%5E2
A=%28x%5E2%2B4x%2B4%29units%5E2
so, your answer is: %28x%5E2%2B4x%2B4%29units%5E2
