Have you tried anything yet? Where does the expression tend to as x goes to -1?

Where is your attempt at a solution? I know calculus can be confusing when you start, but this problem seems pretty straight forward.

well, i used the method of substitution and if my algebra is correct i came out with -6/7 but in my solutions manual that answer is incorrect, then i try to factor the top but it didn't seem to factor out. although, i haven't took college algebra in awhile, so i am a little rusty on my factoring.

What did the answer manual say?

-2/3 , opps i wrote the problem down wrong so it is actually
x3-6x2+11x - 6
x3+4x2-19x + 14
