But when you have zero over zero, this is indeterminate form, and it doesn't mean necessarily that your limit does not exist. And as we'll see in this video and many future ones, there are tools at our disposal to address this, and we will look at one of them. Now the tool that we're gonna look at is, is there another way of rewriting this expression so that we can evaluate its limit without getting the zero over zero? Well let's just rewrite, let's just take this, let me give it, so let's take this thing right over here, and let's say this is g of x. So essentially what we're trying to do is find the limit of g of x as x approaches negative one. So we could write g of x is equal to x plus one, and the whole reason why I'm defining it as g of x is just to be able to think of it more clearly as a function and manipulate the function, and then think about similar functions, over x plus five minus two, or x plus one over the square root of x plus five minus two. Now the technique we're gonna use is, when you get this indeterminate form, and if you have a square root in either the numerator or the denominator, it might help to get rid of that square root.
