Solution for x+6/x-6=0 equation: 


D( x )

x = 0

x = 0

x = 0

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

x+6/x-6 = 0

1*x^1+6*x^-1-6*x^0 = 0

(1*x^2-6*x^1+6*x^0)/(x^1) = 0 // * x^2

x^1*(1*x^2-6*x^1+6*x^0) = 0

x^1

x^2-6*x+6 = 0

x^2-6*x+6 = 0

DELTA = (-6)^2-(1*4*6)

DELTA = 12

DELTA > 0

x = (12^(1/2)+6)/(1*2) or x = (6-12^(1/2))/(1*2)

x = (2*3^(1/2)+6)/2 or x = (6-2*3^(1/2))/2

x in { (6-2*3^(1/2))/2, (2*3^(1/2)+6)/2} 

x in { (6-2*3^(1/2))/2, (2*3^(1/2)+6)/2 }
