This is the same thing as u of x over, you could view the one in the denominator as v of x. So that one right there is v of x. And so if you're taking the derivative of something that can be expressed in this way as the quotient of two different functions, well then you could use the quotient rule. And I'll give you my little aside, like I always do, the quotient rule, if you ever forget it, it can be derived from the product rule. And we have videos there, because the product rule's a little bit easier to remember. But what I can do is just say, look, dy dx, if y is just u of x over v of x, I'm just gonna restate the quotient rule. This is going to be, this is going to be the derivative of the function in the numerator.
