Solving polynomial

  1. Apr 3, 2005 #1

    can anyone show me how to solve this:

    x^(3/2) + (1+x^3)^(1/2)

    i want to get it to so that there's only 1 term of x. but i don't know how to expand the squared root. any help is appreciated.

    You have

    [tex]\sqrt{x^3} + \sqrt{1+x^3} =0[/tex]


    put one member on the other side, square both side.

    no, that's the problem. i don't have it "=0". i just have one to simplify the expression.
