    i suppose you want to differentiate with respect to x, that is, to find dy/dx?

    just differentiate regularly, using the quotient or product rule. when you differentiate a y-term, attach "dy/dx" to it, to say, you "differentiated a y-term with respect to x." similarly, when you differentiate the x-term, you would attach dx/dx, but you don't write it, because that is just 1

    try it, what do you get?

    As the guy above said, use the quotient rule, find the derivative.

    After, use the same dy/dx, and then when you get y', you already know y' is the first derivative, so plug that it and the rest is algebra.
