8/x+1/2 = 5/3-((3/2)*x) // - 5/3-((3/2)*x)
(3/2)*x+8/x+1/2-(5/3) = 0
(3/2)*x+8/x+1/2-5/3 = 0
3/2*x^1+8*x^-1-7/6*x^0 = 0
(3/2*x^2-7/6*x^1+8*x^0)/(x^1) = 0 // * x^2
x^1*(3/2*x^2-7/6*x^1+8*x^0) = 0
x^1
(3/2)*x^2+(-7/6)*x+8 = 0
(3/2)*x^2+(-7/6)*x+8 = 0
DELTA = (-7/6)^2-(4*8*(3/2))
DELTA = -1679/36
DELTA < 0
