3x%2F%28x%5E2%2B3x-10%29-4%2F%28x%2B5%29 Factor
3x%2F%28%28x%2B5%29%28x-2%29%29-4%2F%28x%2B5%29 The LCD is (x+5)(x-2), whatever you do to the denominator to get that you also do to the numerator.
3x%2F%28%28x%2B5%29%28x-2%29%29-4%28x-2%29%2F%28%28x%2B5%29%28x-2%29%29
%283x-4%28x-2%29%29%2F%28%28x%2B5%29%28x-2%29%29
%283x-4x%2B8%29%2F%28%28x%2B5%29%28x-2%29%29
%28-x%2B8%29%2F%28%28x%2B5%29%28x-2%29%29 Some teachers prefer that you don't lead with a negative, so:
%288-x%29%2F%28%28x%2B5%29%28x-2%29%29
Happy Calculating!!!
