I need help with a math problem. I tried several times but none of my solutions are an answer.

Question

Multiply:

20x/(x+1)^2 * x/20

A. x^2/X^2+2x+1

B. 1

C. x

D. 1/ (x+1)^2

Answer 1

The answer is A. The 20 in the numerator cancels out the 20 in the denominator. So you're left with x² on top. They expanded out the (x+1)² in the denominator to get x² + 2x + 1.

Answer 2

the answer should be A. because 20x^2 / 20(x+1)^2 = x^2/(x+1)^2 = x^2 / (x^2 +2x + 1 )
