Hello everyone. We just started working with exact equations and i'm confused on what I do next! here is the problem:(adsbygoogle = window.adsbygoogle || []).push({});

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
