x in (-oo:0) U (0:+oo)
-1/x-6 = 4-((3/2)*x)+12 // - 4-((3/2)*x)+12
(3/2)*x-1/x-12-6-4 = 0
3/2*x^1-1*x^-1-22*x^0 = 0
(3/2*x^2-22*x^1-1*x^0)/(x^1) = 0 // * x^2
x^1*(3/2*x^2-22*x^1-1*x^0) = 0
x^1
(3/2)*x^2-22*x-1 = 0
(3/2)*x^2-22*x-1 = 0
DELTA = (-22)^2-(-1*4*(3/2))
DELTA = 490
DELTA > 0
x = (490^(1/2)+22)/(2*(3/2)) or x = (22-490^(1/2))/(2*(3/2))
x = (7*10^(1/2)+22)/3 or x = (22-7*10^(1/2))/3
x in { (22-7*10^(1/2))/3, (7*10^(1/2)+22)/3}
