Integral with bisquare function

[player1_1_1]

Homework Statement

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?

sorry for long time waiting, i wasnt here for a moment.i think that "precalculus mathematics" is good subforum for this?if not, please explain why:D

Because it's calculus - an integral and all.
