Now let's think about the limit as x approaches one from the right-hand side. Of, once again, I could write g of x minus g of one, but g of one is just zero, so I'll just write g of x over x minus one. Well what's g of x now? Well it's x minus one squared. So instead of writing g of x, I could write this as x minus one squared over x minus one. And so as long as x does not equal one, and we're just doing the limit, we're saying as we approach one from the right-hand side, well this expression right over here, you have x minus one squared divided by x minus one, well that's just going to give us x minus one. X minus one squared divided by x minus one is just going to be x minus one.
