# How do you find the Vertical, Horizontal, and Oblique Asymptote given (x^2-64)/(x-8)?

The numerator factorizes to $\left(x - 8\right) \left(x + 8\right)$ so you can cancel the $x - 8$, so you are left with $x + 8$. This is a straight line with gradient $1$, which, arguably, is a degenerate case of an oblique asymptote.
