Directions: Solve graphically:

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


I just don't know how to approach this?!

  • algebra -

    let x^(1/3) = t

    so t^2 + t - 2 = 0
    (t+2)(t-1) = 0
    t = -2 or t=1

    x^(1/3) = -2 or x^(1/3) = 1
    x = -8 or x = 1

    Don't know how solving this "graphically" can be easier?
    Are you supposed to use a graphing calculator?

  • algebra -

    Thats just what the directions say..

    But thank you so much, You Rock!!
