x in (-oo:+oo)
(1/6)*x^2-((1/8)*x) = 1 // - 1
(1/6)*x^2-((1/8)*x)-1 = 0
(1/6)*x^2+(-1/8)*x-1 = 0
1/6*x^2-1/8*x-1 = 0
DELTA = (-1/8)^2-(-1*1/6*4)
DELTA = 131/192
DELTA > 0
x = ((131/192)^(1/2)+1/8)/(1/6*2) or x = (1/8-(131/192)^(1/2))/(1/6*2)
x = 3*((131/192)^(1/2)+1/8) or x = 3*(1/8-(131/192)^(1/2))
x in { 3*(1/8-(131/192)^(1/2)), 3*((131/192)^(1/2)+1/8) }
