Hello everyone. We just started working with exact equations and I'm confused on what I do next! here is the problem:
Use the "mixed partials" check to see if the following differential equation is exact.
If it is exact find a function F(x,y) whose level curves are solutions to the differential equation

Here is my work, I submitted:
2*y^2+2*x^2-4 which was wrong.
