Find the limit as x goes to -3. (2 - Sqrt(x^2 - 5))/(x + 3)

sorry for the sloppiness if I knew the codes or where to get the latex codes from I'd write this better. Hopefully someone can write this in the proper form so its easier to read. But I know the first step is to rationalize the limit by multiplying both the numerator and denominator by (2 + sqrt(x^2 - 5)). After this I get a little confused.
