$\displaystyle f(x) = \frac{x^3}{(x-11)^2}$

On ones like this I usually just start with $\displaystyle \frac{1}{1-x}$ & differentiate and then multiply and divide terms back in to get my final power series, but with the$\displaystyle ~x^3~ $on top, how should I work this? I thought about just factoring out one of the x's on top and setting it outside the series, can I do that?
