x in (-oo:+oo)
2.483*10^-5 = (x^2)/0.2-x // - (x^2)/0.2-x
x-((x^2)/0.2)+2.483*10^-5 = 0
x-5*x^2+2.483*10^-5 = 0
x-5*x^2+0.00002483 = 0
DELTA = 1^2-(-5*0.00002483*4)
DELTA = 1.0004966
DELTA > 0
x = (1.0004966^(1/2)-1)/(-5*2) or x = (-1.0004966^(1/2)-1)/(-5*2)
x = (1.0004966^(1/2)-1)/(-10) or x = (1.0004966^(1/2)+1)/10
x in { (1.0004966^(1/2)-1)/(-10), (1.0004966^(1/2)+1)/10 }
