And if I can just evaluate it at x equals negative one, I feel pretty good, I feel pretty good. So once again, we're now going and factoring. We're able to factor. We evaluate, we simplify it.

We were able to get 3 4ths and so we can feel pretty good that the limit here in this situation is 3 4ths. Now let's, and I would categorize what we've seen so far as the bulk of the limit exercises that you will likely encounter.
