D( x )
x = 0
x = 0
x = 0
x in (-oo:0) U (0:+oo)
x = 1/x-1 // - 1/x-1
x-(1/x)+1 = 0
x-x^-1+1 = 0
1*x^1-1*x^-1+1*x^0 = 0
(1*x^2+1*x^1-1*x^0)/(x^1) = 0 // * x^2
x^1*(1*x^2+1*x^1-1*x^0) = 0
x^1
x^2+x-1 = 0
x^2+x-1 = 0
DELTA = 1^2-(-1*1*4)
DELTA = 5
DELTA > 0
x = (5^(1/2)-1)/(1*2) or x = (-5^(1/2)-1)/(1*2)
x = (5^(1/2)-1)/2 or x = (-(5^(1/2)+1))/2
x in { (-(5^(1/2)+1))/2, (5^(1/2)-1)/2}
x in { (-(5^(1/2)+1))/2, (5^(1/2)-1)/2 }
