1. The problem statement, all variables and given/known data (8x^2y^3-2y^4)dx+(5x^3y^2-8xy^3)dy=0 2. Relevant equations 3. The attempt at a solution I've already tried the most logical steps. The equation isn't exact and I couldn't find an integrating factor to make it exact. It's also not homogeneous or separable. I have to be making an error somewhere. I've done all my other questions but this one is just killing me. Help please!
