Solution for 5z^2/3+9z^1/3-2=0 equation: 


z in (-oo:+oo)

(5*z^2)/3+(9*z^1)/3-2 = 0

(5*z^2)/3+(9*z)/3-2 = 0

5/3*z^2+3*z-2 = 0

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

DELTA = 67/3

DELTA > 0

z = ((67/3)^(1/2)-3)/(5/3*2) or z = (-(67/3)^(1/2)-3)/(5/3*2)

z = 3/10*((67/3)^(1/2)-3) or z = -3/10*((67/3)^(1/2)+3)

z in { -3/10*((67/3)^(1/2)+3), 3/10*((67/3)^(1/2)-3) }
