x in (-oo:+oo)
(1/6)*x^2-((1/3)*x) = 1 // - 1
(1/6)*x^2-((1/3)*x)-1 = 0
(1/6)*x^2+(-1/3)*x-1 = 0
1/6*x^2-1/3*x-1 = 0
DELTA = (-1/3)^2-(-1*1/6*4)
DELTA = 7/9
DELTA > 0
x = ((7/9)^(1/2)+1/3)/(1/6*2) or x = (1/3-(7/9)^(1/2))/(1/6*2)
x = 3*((7/9)^(1/2)+1/3) or x = 3*(1/3-(7/9)^(1/2))
x in { 3*(1/3-(7/9)^(1/2)), 3*((7/9)^(1/2)+1/3) }
