So on the left-hand side, and actually all the stuff that's not a dy dx I'm going to write in green. So on the left-hand side, we're just left with 3 times y minus x squared times dy dx. dy, the derivative of y with respect to x, is equal to, I'm just going to subtract this from both sides, is equal to negative 2x plus this. So I could write it as 3 times y minus x squared plus, sorry, minus 2x. So we're adding this to both sides, and we're subtracting this from both sides, minus 2x. And then to solve for dy dx, we've done this multiple times already, to solve for the derivative of y with respect to x. The derivative of y with respect to x is going to be equal to 3 times y minus x squared minus 2x, all of that over this stuff, 3 times y minus x squared.
