D( x )
x = 0
x = 0
x = 0
x in (-oo:0) U (0:+oo)
x-(1/x)-1 = 1 // - 1
x-(1/x)-1-1 = 0
x-x^-1-1-1 = 0
1*x^1-1*x^-1-2*x^0 = 0
(1*x^2-2*x^1-1*x^0)/(x^1) = 0 // * x^2
x^1*(1*x^2-2*x^1-1*x^0) = 0
x^1
x^2-2*x-1 = 0
x^2-2*x-1 = 0
DELTA = (-2)^2-(-1*1*4)
DELTA = 8
DELTA > 0
x = (8^(1/2)+2)/(1*2) or x = (2-8^(1/2))/(1*2)
x = (2*2^(1/2)+2)/2 or x = (2-2*2^(1/2))/2
x in { (2-2*2^(1/2))/2, (2*2^(1/2)+2)/2}
x in { (2-2*2^(1/2))/2, (2*2^(1/2)+2)/2 }
