You might just want to inspect kind of the structure of this expression and think about, well when is that going to be greater than zero? Or we could do it a little bit more methodically. We could say, well let's look at the critical points or the critical values for g. So critical, critical points for g. And just to remind ourselves what critical points are, that is when g prime of x is equal to zero or g prime of x is undefined, is undefined. And we have videos on critical points or critical values. And why those are relevant is those are the places, those are the possible places where the sign could change, the sign of g prime could change. So when is g prime of x equal to zero? Well the way to get g prime of x equal to zero is getting the numerator equal to zero and that's only going to happen if x squared is equal to zero or if x is equal to zero.
