This might be a little bit clearer in terms of the chain rule. The derivative of y as a function of x squared with respect to y of x, so the derivative of something squared, the derivative of something squared with respect to that something, times the derivative of that something with respect to x. This is just the chain rule. I wanna say it over and over again. This is just the chain rule. So let's do that. What do we get on the right-hand side over here?
