(x^2-y^2)^2=(x+y)^3
I tried to use the chain rule on both sides but it didn't work because y needs to have the chain rule used on it explicitly and if i differentiate y explicitly then use the chain rule on everything i would be finding the 2nd derivative. So how do i differentiate this?

For starters, what is the derivative with respect to x of [itex](x^2-y^2)^2[/itex]? Of [itex](x+y)^3[/itex]?

What does the question ask of you? That you find dy/dx as a function of x only, or simply to implicitly differentiate it?
