So it's x minus four over x minus four times square root of x plus two. Square root of x plus two. Well this was useful because now I can cancel out x equals four, or x minus four, right over here. And once again, if I wanted it mathematically to be the exact same expression, I would say well, now this is going to be equal to one over the square root of x plus two for x does not equal four. But we can definitely see what this function is approaching if we just now substitute x equals four into this simplified expression. And so that's just gonna be one over, so if we just substitute, if we just substitute x equals four here, you get one over square root of four plus two, which is equal to 1 4th. And once again, you can feel pretty good that this is going to be your limit.
