You can say x=y^6.
Then you don't have any root left.
After that, you can divide the numerator by the denominator.
You get an immediate integral and a integral which can be resolved using the partial fractions method.
Then, put back x in your answer.
You should get something with a square root of x,a few logs (probably two) and a tan-1.
