The Attempt at a Solution

i kind of get how to do normal ODEs but this one would have a function in terms of y and x that i would have to intergrate as the intergrating factor - i don't think this is the right way to go.

Have you learned what is an exact differential equation?

 

[wombat4000]

i think so

 

[Defennder]

Well, then you should know how to solve this. That was essentially how to solve it. Find the potential function.
