5*x-(5/x)-1 = 0
5*x-5*x^-1-1 = 0
5*x^1-5*x^-1-1*x^0 = 0
(5*x^2-1*x^1-5*x^0)/(x^1) = 0 // * x^2
x^1*(5*x^2-1*x^1-5*x^0) = 0

5*x^2-x-5 = 0
5*x^2-x-5 = 0
DELTA = (-1)^2-(-5*4*5)
DELTA = 101
DELTA > 0
x = (101^(1/2)+1)/(2*5) or x = (1-101^(1/2))/(2*5)
x = (101^(1/2)+1)/10 or x = (1-101^(1/2))/10
x in { (1-101^(1/2))/10, (101^(1/2)+1)/10}
