Solution for x^2/9-4x/3-2=0 equation: 


x in (-oo:+oo)

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

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

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

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

DELTA = 8/3

DELTA > 0

x = ((8/3)^(1/2)+4/3)/(1/9*2) or x = (4/3-(8/3)^(1/2))/(1/9*2)

x = 9/2*((8/3)^(1/2)+4/3) or x = 9/2*(4/3-(8/3)^(1/2))

x in { 9/2*(4/3-(8/3)^(1/2)), 9/2*((8/3)^(1/2)+4/3) }
