1. The problem statement, all variables and given/known data
integral:
$$\int\sqrt{ax^4+bx^2+c}\mbox{d}x$$
normally its elliptic type but here its bisquare function - any ideas?

I'm pretty sure that it's still elliptic - so not much chance of a closed form solution. Out of curiousity, why did you post this in the precalculus forum?

Because it's calculus - an integral and all.
