Solution for 2/3x^2-1/6x-1/2=0 equation: 


x in (-oo:+oo)

(2/3)*x^2-((1/6)*x)-(1/2) = 0

(2/3)*x^2+(-1/6)*x-1/2 = 0

2/3*x^2-1/6*x-1/2 = 0

DELTA = (-1/6)^2-(-1/2*2/3*4)

DELTA = 49/36

DELTA > 0

x = ((49/36)^(1/2)+1/6)/(2/3*2) or x = (1/6-(49/36)^(1/2))/(2/3*2)

x = 1 or x = -3/4

x in { -3/4, 1 }
