How would I go about solving the following: Lim 2x squared + 5x +2 ---------------- x squared + 2x -8 x-> -2

So it looks a bit better, we're talking about: $\lim_{x \rightarrow -2} \frac{2x^2 + 5x + 2}{x^2 + 2x - 8}$

I started by factoring it and got $\left[ (x+4)(x+5) \right]\div\left[ (x-4)(x+2) \right]$ The think is that I can not get rid of anything on the bottom. What do I do.
