(4/2)*x-2 = 2/x // - 2/x
(4/2)*x-(2/x)-2 = 0
(4/2)*x-2*x^-1-2 = 0
2*x^1-2*x^-1-2*x^0 = 0
(2*x^2-2*x^1-2*x^0)/(x^1) = 0 // * x^2
x^1*(2*x^2-2*x^1-2*x^0) = 0
x^1
2*x^2-2*x-2 = 0
2*x^2-2*x-2 = 0
DELTA = (-2)^2-(-2*2*4)
DELTA = 20
DELTA > 0
x = (20^(1/2)+2)/(2*2) or x = (2-20^(1/2))/(2*2)
x = (2*5^(1/2)+2)/4 or x = (2-2*5^(1/2))/4
