%28%28n%5E2-n-20%29%29%2F%282n%5E2%29 x %28%28n%5E2%2B5n%29%29%2F%28%28n%5E2-25%29%29 =

You can so some serious factoring here, note that (x^2 - 25) is the difference of squares:
%28%28n-5%29%28n%2B4%29%29%2F%282n%5E2%29 x %28n%28n%2B5%29%29%2F%28%28n-5%29%28n%2B5%29%29 =
:
Cancel the following:
(n-5)'s; (n+5)'s; n cancels into 2n^2; resulting in:
:
%28%28n%2B4%29%29%2F%282n%29

Did this make sense to you? Any questions?
