    Take derivative of both sides then divide both sides by 3y². Can you handle it? No?

    OK, Do you know that derivative is distributive? Just take derivative of each term separably.

    I think what he is trying to say is look at it this way dy/dx: (dy/dx 4x^2+ dy/dx 3xy^2- dy/dx 6x^2y=y^3. but I too am still learning this junk and its fairly new to me. I do know you have to use the sum laws (i think)
