All right. So we're given this expression here and were asked to, uh what numbers? What? What values for the variables here will cause this expression to be undefined. And so here, that's when the denominator it is undefined when the denominator is equal to zero. And so all we do is set. The denominator equals zero and we get solving for X, we get X is equal to negative five. So for the value where X is equal to negative five this expression he up here is on defined.
