Solution for x-8/x-9 equation: 


D( x )

x = 0

x = 0

x = 0

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

x-(8/x)-9 = 0

x-8*x^-1-9 = 0

1*x^1-8*x^-1-9*x^0 = 0

(1*x^2-9*x^1-8*x^0)/(x^1) = 0 // * x^2

x^1*(1*x^2-9*x^1-8*x^0) = 0

x^1

x^2-9*x-8 = 0

x^2-9*x-8 = 0

DELTA = (-9)^2-(-8*1*4)

DELTA = 113

DELTA > 0

x = (113^(1/2)+9)/(1*2) or x = (9-113^(1/2))/(1*2)

x = (113^(1/2)+9)/2 or x = (9-113^(1/2))/2

x in { (9-113^(1/2))/2, (113^(1/2)+9)/2} 

x in { (9-113^(1/2))/2, (113^(1/2)+9)/2 }
