Directions: Solve graphically:

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

I just dont know how to approach this?!

**Reiny**, Wednesday, December 8, 2010 at 1:34pmlet 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?
