Simplify:
%28%28x-y%29%2F%28x%2By%29%29%2B%28%28x%2By%29%2F%28x-y%29%29 I hope I have this right! Add the two fractions. The LCD is %28x%2By%29%28x-y%29
Do you see how we get this? Now perform the indicated multiplications.
Simplify by combining like-terms.
%282x%5E2%2B2y%5E2%29%2F%28%28x%5E2-y%5E2%29%29 Factor the 2 in the numerator.
2%28%28x%5E2%2By%5E2%29%2F%28x%5E2-y%5E2%29%29...and this is as far as we can go!
