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? Well, it doesn't change, so it's just going to be equal to zero. All right, now we can solve for our first derivative of y with respect to x. Let's do that.
