I assume you mean like the following:
%28%28n%5E2-n-20%29%2F2n%5E2%29%28%28n%5E2%2B5n%29%2F%28n%5E2-25%29%29
Let's do some manipulation on both before we multiply.
%28n%5E2-n-20%29%2F2n%5E2=%28%28n-5%29%28n%2B4%29%29%2F2n%5E2

That simplifies some of the multiplication

%28%28n%5E2-n-20%29%2F2n%5E2%29%28%28n%5E2%2B5n%29%2F%28n%5E2-25%29%29=%28n%2B4%29%2F2n
