Find the Limit:

lim {(x^4 - 16) / (x^3 - 8 ) }
x->2

I can't figure it out, and I have tried the conjugate method. Just can't find the right one.

Have you tried factoring? It works. Turns out it's the limit is two.

Yes, factoring would be the way to go. (Hint: Difference of squares -- twice -- and difference of cubes.)
