Don't know where to start.
I tried a few substitution but doesn't yield anything.

The answer isn't pretty at all. Try it out at integrator.wolfram.com There's an imaginary number in it, along with "elliptical integrals", whatever that may mean. Probably there isn't any antiderivative which you can express in elementary form.
