15%2B3y-5x%5E2-x%5E2y Start with the given expression

%2815%2B3y%29%2B%28-5x%5E2-x%5E2y%29 Group like terms


3%285%2By%29-x%5E2%285%2By%29 Factor out the GCF 3 out of the first group. Factor out the GCF -x%5E2 out of the second group


%283-x%5E2%29%285%2By%29 Since we have the common term 5%2By, we can combine like terms

So 15%2B3y-5x%5E2-x%5E2y factors to %283-x%5E2%29%285%2By%29
