Limit as x approaches negative one of this rational expression. And let's try to evaluate it. You get negative one squared, which is one, minus negative one, which is plus one, minus two, so you get zero in the numerator. And then in the denominator, you have negative one squared, which is one, minus two times negative one, so plus two minus three, which is equal to zero. Now this is known as indeterminate form. And so on our flow chart, we then continue to the right side of it. And so here's a bunch of techniques for trying to tackle something in indeterminate form.
