You can put this solution on YOUR website!
%28x%5E2%2B%283x%2Fx%5E2%29-3x-18%29
you have a fraction so you always multiply to get rid of the fraction. multiply everything by x^2
%28%283x%2Fx%5E2%29%2B%28x%5E2-3x-18%29%29
%28%283x%2Fx%5E2%29%2B%28x-6%29%28x%2B3%29%29
%283x%29%2Bx%5E2%28x-6%29%28x%2B3%29%29
