x in (-oo:0) U (0:+oo)
(1/3)*x+(1/2)*x = 1/6-(1/x) // - 1/6-(1/x)
(1/3)*x+(1/2)*x+1/x-(1/6) = 0
(1/3)*x+(1/2)*x+1/x-1/6 = 0
5/6*x^1+1*x^-1-1/6*x^0 = 0
(5/6*x^2-1/6*x^1+1*x^0)/(x^1) = 0 // * x^2
x^1*(5/6*x^2-1/6*x^1+1*x^0) = 0
x^1
(5/6)*x^2+(-1/6)*x+1 = 0
(5/6)*x^2+(-1/6)*x+1 = 0
DELTA = (-1/6)^2-(1*4*(5/6))
DELTA = -119/36
DELTA < 0
