If i have rational function and it has a numerator that can be factored and the denominator is already factored out would I simplify by factoring the numerator?

The question is:

((x^2)-4)/ ((x-2)(x+3))

and then cancelling out the x-2 from both the denominator and the numerator leaving me with (x+2)/(X+3)? And then go from there to find the limit?
