X in (-oo:+oo)
(X^2)/3-((2*X)/3)+1/6 = 0
(X^2)/3+(-2/3)*X+1/6 = 0
1/3*X^2-2/3*X+1/6 = 0
DELTA = (-2/3)^2-(1/6*1/3*4)
DELTA = 2/9
DELTA > 0
X = ((2/9)^(1/2)+2/3)/(1/3*2) or X = (2/3-(2/9)^(1/2))/(1/3*2)
X = 3/2*((2/9)^(1/2)+2/3) or X = 3/2*(2/3-(2/9)^(1/2))
X in { 3/2*(2/3-(2/9)^(1/2)), 3/2*((2/9)^(1/2)+2/3) }
