x = 0
x in (-oo:0) U (0:+oo)
2*x+2*x-(1/x)-(3/1)+2 = 0
2*x+2*x-x^-1-3+2 = 0
4*x^1-1*x^-1-1*x^0 = 0
(4*x^2-1*x^1-1*x^0)/(x^1) = 0 // * x^2
x^1*(4*x^2-1*x^1-1*x^0) = 0

4*x^2-x-1 = 0
4*x^2-x-1 = 0
DELTA = (-1)^2-(-1*4*4)
DELTA = 17
DELTA > 0
x = (17^(1/2)+1)/(2*4) or x = (1-17^(1/2))/(2*4)
x = (17^(1/2)+1)/8 or x = (1-17^(1/2))/8
