Solution for x-3/x+3 equation: 


D( x )

x = 0

x = 0

x = 0

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

x-(3/x)+3 = 0

x-3*x^-1+3 = 0

1*x^1-3*x^-1+3*x^0 = 0

(1*x^2+3*x^1-3*x^0)/(x^1) = 0 // * x^2

x^1*(1*x^2+3*x^1-3*x^0) = 0

x^1

x^2+3*x-3 = 0

x^2+3*x-3 = 0

DELTA = 3^2-(-3*1*4)

DELTA = 21

DELTA > 0

x = (21^(1/2)-3)/(1*2) or x = (-21^(1/2)-3)/(1*2)

x = (21^(1/2)-3)/2 or x = (-(21^(1/2)+3))/2

x in { (-(21^(1/2)+3))/2, (21^(1/2)-3)/2} 

x in { (-(21^(1/2)+3))/2, (21^(1/2)-3)/2 }
