X in (-oo:+oo)
0.0000018 = (X*(X+0.5))/0.5-X // - (X*(X+0.5))/0.5-X
X-((X*(X+0.5))/0.5)+0.0000018 = 0
X-2*X*(X+0.5)+0.0000018 = 0
X-2*X*(X+0.5)+0.0000018 = 0
0.0000018-2*X^2 = 0
0.0000018-2*X^2 = 0
-2*X^2 = -0.0000018 // : -2
X^2 = 0.0000009
X^2 = 0.0000009 // ^ 1/2
abs(X) = 0.0000009^(1/2)
X = 0.0000009^(1/2) or X = -0.0000009^(1/2)
X in { 0.0000009^(1/2), -0.0000009^(1/2) }
