What do we get on the right-hand side over here? And I'll write it over here as well. This would be equal to the derivative of y squared with respect to y is just going to be two times y, two times y, just an application of the chain rule. And the derivative of y with respect to x, well, we don't know what that is, so we're just gonna leave that as times the derivative of y times the derivative of y with respect to x. So let's just write this down over here. So what we have is two x, two x plus, two x plus derivative of something squared with respect to that something is two times the something. In this case, the something is y, so two times y, and then times the derivative of y, the derivative of y with respect to x.
