If ##y(x-y)^2=x##, then find
The Attempt at a Solution
I tried expanding the given equation. That gives me a cubic in y. I found no way to solve the cubic equation. I plugged the equation in Wolfram Alpha to see if it gives any nice solution but nope, no luck there too. Now I think that this is some sort of trick question but I don't really know where to begin.
Any help is appreciated. Thanks!
