Evaluate the following indefinite integral: ∫ ((x) / (1 + x^4))dx

Evaluate the following indefinite integral:

∫ ((x) / (1 + x^4))dx

Any and all help is much appreciated! Thanks so much in advance!

Hint: let u = x^2, then du = 2x dx

That's what happens when I attempt anything in mathematics: Barf soup!!
