Thread: Differential Equation help!

I'm having a real hard time solving this:



I have tried mixing everything around and I can't seem to remember how to get y and dy, x and dx on separate sides of the equation. I know I am missing one step!

Any help would be great!
Cheers.

Do you know anything about the integrating factor? This is a scenario where it's applicable. For a little info on the integrating factor, see post #2 of my differential equations tutorial.

Yeah I do but the example I have in my lecture notes is quite different.

Would I(x) here be e^(5x) or e^(-5x)? Does it matter?

It does matter. The integrating factor would be
