Solution for 7x-6/8x-9=x-6/x-8 equation: 


D( x )

x = 0

x = 0

x = 0

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

7*x-((6/8)*x)-9 = x-(6/x)-8 // - x-(6/x)-8

7*x-((6/8)*x)-x+6/x-9+8 = 0

7*x+(-3/4)*x-x+6/x-9+8 = 0

21/4*x^1+6*x^-1-1*x^0 = 0

(21/4*x^2-1*x^1+6*x^0)/(x^1) = 0 // * x^2

x^1*(21/4*x^2-1*x^1+6*x^0) = 0

x^1

(21/4)*x^2-x+6 = 0

(21/4)*x^2-x+6 = 0

DELTA = (-1)^2-(4*6*(21/4))

DELTA = -125

DELTA < 0

x in { } 

x belongs to the empty set
