Well, the derivative with respect to x of y squared, we're gonna use the chain rule here. First, we can take the derivative of y squared with respect to y, which is going to be equal to two y. And then that times the derivative of y with respect to x. Once again, this comes straight out of the chain rule. And then from that, we will subtract, what's the derivative of x squared with respect to x? Well, that's just going to be two x. And then last but not least, what is the derivative of a constant with respect to x?
