This problem isn't too hard

What you are going to have to do is remember your difference of squares formula
%28a%5E2-b%5E2%29+=+%28a-b%29%28a%2Bb%29
So the problem is:
%28%28a%5E2-36%29%2F%2810a%29%29%28%282a%29%2F%28a%2B6%29%29

The first step would be to factor the numerator on the left term:

%28%28a%2B6%29%28a-6%29%2F%2810a%29%29%28%282a%29%2F%28a%2B6%29%29}
