x in (-oo:0) U (0:+oo)
2/x-((3/2)*x) = 1/3 // - 1/3
2/x-((3/2)*x)-(1/3) = 0
(-3/2)*x+2/x-1/3 = 0
2*x^-1-3/2*x^1-1/3*x^0 = 0
(2*x^0-3/2*x^2-1/3*x^1)/(x^1) = 0 // * x^2
x^1*(2*x^0-3/2*x^2-1/3*x^1) = 0

(-3/2)*x^2+(-1/3)*x+2 = 0
(-3/2)*x^2+(-1/3)*x+2 = 0
DELTA = (-1/3)^2-(2*4*(-3/2))
DELTA = 109/9
DELTA > 0
x = ((109/9)^(1/2)-(-1/3))/(2*(-3/2)) or x = (-(-1/3)-(109/9)^(1/2))/(2*(-3/2))
x = ((109/9)^(1/2)+1/3)/(-3) or x = (1/3-(109/9)^(1/2))/(-3)
x in { ((109/9)^(1/2)+1/3)/(-3), (1/3-(109/9)^(1/2))/(-3)}
