1. The problem statement, all variables and given/known data x^4 + y^4 - xy^2 = x^2y 2. Relevant equations None. However, I'm using "^" to represent an exponent operation. 3. The attempt at a solution Not sure. That's why I'm asking. It just feels to me that everything is an unlike term and thus you can't do anything. Is that correct here? Thanks for the help everyone!
