simplify the rational expression:
%28x%5E2+%2B3x+-+10%29%2F%28x%5E2+%2B+x+-20%29

Factor numerator and denominator:

%28%28x%2B5%29%28x-2%29%29%2F%28%28x%2B5%29%28x-4%29%29

Cancel the %28x%2B5%29's

%28cross%28%28x%2B5%29%29%28x-2%29%29%2F%28cross%28%28x%2B5%29%29%28x-4%29%29

All that's left is

%28x-2%29%2F%28x-4%29
