First combine like terms to get
x%5E2-15%2Fx%5E2-6x%2B15
next add fractions using a common denominator of x^2 to get
%28x%5E4-6x%5E3%2B15x%5E2+-15%29%2Fx%5E2
we could group some of the numerator as
%28%28x%5E4-6x%5E3%29%2B%2815x%5E2+-15%29%29%2Fx%5E2
factoring each group gives us
%28x%5E3%28x-6%29+%2B15%28x%2B1%29%28x-1%29%29%2Fx%5E2
