X minus one squared divided by x minus one is just going to be x minus one. And this limit, well this expression right over here is going to be continuous and defined for sure all x's that are not equaling one. Actually let me, well it was before it was this, x minus one squared over x minus one. This thing right over here, as I said, it's not defined for x equals one, but it is defined for anything not, for x does not equal one, and we're just approaching one. And if we wanted to simplify this expression, it would get, this would just be, I think I just did this, but I'm just making sure I'm doing it right. This is going to be the same thing as that for x not being equal to one. Well this is just going to be zero.
