D( x )
x = 0
x = 0
x = 0
x in (-oo:0) U (0:+oo)
x = 1/x+5 // - 1/x+5
x-(1/x)-5 = 0
x-x^-1-5 = 0
1*x^1-1*x^-1-5*x^0 = 0
(1*x^2-5*x^1-1*x^0)/(x^1) = 0 // * x^2
x^1*(1*x^2-5*x^1-1*x^0) = 0
x^1
x^2-5*x-1 = 0
x^2-5*x-1 = 0
DELTA = (-5)^2-(-1*1*4)
DELTA = 29
DELTA > 0
x = (29^(1/2)+5)/(1*2) or x = (5-29^(1/2))/(1*2)
x = (29^(1/2)+5)/2 or x = (5-29^(1/2))/2
x in { (5-29^(1/2))/2, (29^(1/2)+5)/2}
