Solution for 1=2x-2/x equation: 


D( x )

x = 0

x = 0

x = 0

x in (-oo:0) U (0:+oo)

1 = 2*x-(2/x) // - 2*x-(2/x)

2/x-(2*x)+1 = 0

2/x-2*x+1 = 0

2*x^-1-2*x^1+1*x^0 = 0

(1*x^1-2*x^2+2*x^0)/(x^1) = 0 // * x^2

x^1*(1*x^1-2*x^2+2*x^0) = 0

x^1

x-2*x^2+2 = 0

x-2*x^2+2 = 0

DELTA = 1^2-(-2*2*4)

DELTA = 17

DELTA > 0

x = (17^(1/2)-1)/(-2*2) or x = (-17^(1/2)-1)/(-2*2)

x = (17^(1/2)-1)/(-4) or x = (17^(1/2)+1)/4

x in { (17^(1/2)-1)/(-4), (17^(1/2)+1)/4} 

x in { (17^(1/2)-1)/(-4), (17^(1/2)+1)/4 }
