Hello, and welcome to FMH! :)

When I see an ODE in differential form, the first thing I look at (after making sure it's not separable/linear, etc) is to test for exactness. Is this ODE exact?

My=1 (=/) -1 = Nx, M(x,y)=9x^(2)+y-1 & N(x,y)=4y-x

Okay, so what happens when you try to find an integrating factor?
