1. The problem statement, all variables and given/known data
I'd like hints as to how to solve this problem. Thanks!

$$\lim_{x\rightarrow{\inf}}{\frac{x^2-4}{2+x-4x^2}}$$

2. Relevant equations

I think I would begin by dividing out the fraction to get rid of the x^2? Is this the right way to start?

3. The attempt at a solution
