Solve: 3x^(2/3) + 4x^(1/3) - 4 = 0

I need help solving the equation 3x^(2/3) + 4x^(1/3) - 4 = 0. Any help would be greatly appreciated.

Thanks in advance,

Could you let x^(1/3) = u, then you would have 3u^2 + 4u - 4 = 0, solve for u, and make the substitution back?

Yes, thank you very much. This review for my precalc class is getting the best of me. :/

Again, thanks,
