Solution for 4x^2/3-9x^1/3=9 equation: 


x in (-oo:+oo)

(4*x^2)/3-((9*x^1)/3) = 9 // - 9

(4*x^2)/3-((9*x^1)/3)-9 = 0

(4*x^2)/3-3*x-9 = 0

4/3*x^2-3*x-9 = 0

DELTA = (-3)^2-(-9*4/3*4)

DELTA = 57

DELTA > 0

x = (57^(1/2)+3)/(4/3*2) or x = (3-57^(1/2))/(4/3*2)

x = 3/8*(57^(1/2)+3) or x = 3/8*(3-57^(1/2))

x in { 3/8*(3-57^(1/2)), 3/8*(57^(1/2)+3) }
