Let's give ourselves some space. So I'm gonna apply my derivative operator to both sides. I'm gonna take the derivative of the left-hand side with respect to x and the derivative of the right-hand side with respect to x. And so here I'll apply the product rule. First I'll take the derivative of this expression and then multiply that times dy dx and then I'll take the derivative of this expression and multiply it times this. So the derivative of three y squared minus x with respect to x, well that is going to be, so if I take the derivative of three y squared with respect to y, it's going to be six y. And then I have to take the derivative of y with respect to x, so times dy dx.
