Question 263116
First combine like terms to get
{{{x^2-15/x^2-6x+15}}}
next add fractions using a common denominator of x^2 to get
{{{(x^4-6x^3+15x^2 -15)/x^2}}}
we could group some of the numerator as
{{{((x^4-6x^3)+(15x^2 -15))/x^2}}}
factoring each group gives us
{{{(x^3(x-6) +15(x+1)(x-1))/x^2}}}
