simplify %28%28m%5E2-2mn%2Bn%5E2%29%29%2F%28%287m%5E2-7n%5E2%29%29
Factor
%28%28m-n%29%28m-n%29%29%2F%287%28m%5E2-n%5E2%29%29
:
(m^2 - n^2) is the difference of squares and can be factored:
%28%28m-n%29%28m-n%29%29%2F%287%28m-n%29%28m%2Bn%29%29%29
:
Cancel (m-n)
%28%28m-n%29%29%2F%287%28m%2Bn%29%29%29
