Solution for 4x^2/3-15x^1/3-4=0 equation: 


x in (-oo:+oo)

(4*x^2)/3-((15*x^1)/3)-4 = 0

(4*x^2)/3-5*x-4 = 0

4/3*x^2-5*x-4 = 0

DELTA = (-5)^2-(-4*4/3*4)

DELTA = 139/3

DELTA > 0

x = ((139/3)^(1/2)+5)/(4/3*2) or x = (5-(139/3)^(1/2))/(4/3*2)

x = 3/8*((139/3)^(1/2)+5) or x = 3/8*(5-(139/3)^(1/2))

x in { 3/8*(5-(139/3)^(1/2)), 3/8*((139/3)^(1/2)+5) }
