Solution for 2x^2/3-11x^1/3-21=0 equation: 


x in (-oo:+oo)

(2*x^2)/3-((11*x^1)/3)-21 = 0

(2*x^2)/3+(-11/3)*x-21 = 0

2/3*x^2-11/3*x-21 = 0

DELTA = (-11/3)^2-(-21*2/3*4)

DELTA = 625/9

DELTA > 0

x = ((625/9)^(1/2)+11/3)/(2/3*2) or x = (11/3-(625/9)^(1/2))/(2/3*2)

x = 9 or x = -7/2

x in { -7/2, 9 }
