If you want to factor, then...


x%5E2-5xy%2B3x-15y Start with the given expression


%28x%5E2-5xy%29%2B%283x-15y%29 Group the terms in two pairs


x%28x-5y%29%2B3%28x-5y%29 Factor out the GCF x out of the first group. Factor out the GCF 3 out of the second group


%28x%2B3%29%28x-5y%29 Since we have the common term x-5y, we can combine like terms


So x%5E2-5xy%2B3x-15y factors to %28x%2B3%29%28x-5y%29


In other words, x%5E2-5xy%2B3x-15y=%28x%2B3%29%28x-5y%29
