I have found the slant asymptote of $\displaystyle \frac{x^4-6x^3-11x^2+60x+100}{x^3-9x^2+27x-27}$ to be $\displaystyle y=x+3$. Somehow, on it's graph, the slant looks totally off. What is the problem with my math? The factored form that was given is $\displaystyle \frac{(x-5)^2(x+2)^2}{(x-3)^4}$. Thanks!
