Solution for (x^2/3)-(3x^1/3)-4=0 equation: 


x in (-oo:+oo)

(x^2)/3-((3*x^1)/3)-4 = 0

(x^2)/3-x-4 = 0

1/3*x^2-x-4 = 0

DELTA = (-1)^2-(-4*1/3*4)

DELTA = 19/3

DELTA > 0

x = ((19/3)^(1/2)+1)/(1/3*2) or x = (1-(19/3)^(1/2))/(1/3*2)

x = 3/2*((19/3)^(1/2)+1) or x = 3/2*(1-(19/3)^(1/2))

x in { 3/2*(1-(19/3)^(1/2)), 3/2*((19/3)^(1/2)+1) }
