The correct inequality is


Factor the numerator and denominator on the left. The numerator factors as a difference of squares, like
x%5E2-y%5E2+=+%28x%2By%29%28x-y%29

In the denominator you can factor out a common factor between the two terms.

When you have done the factoring, the path to finishing the problem should be easy.
