Solution for x^2/x-9=81/x-9 equation: 


D( x )

x = 0

x = 0

x = 0

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

(x^2)/x-9 = 81/x-9 // - 81/x-9

(x^2)/x-(81/x)-9+9 = 0

(x^2)/x-81*x^-1-9+9 = 0

1*x^1-81*x^-1 = 0

(1*x^2-81*x^0)/(x^1) = 0 // * x^2

x^1*(1*x^2-81*x^0) = 0

x^1

x^2-81 = 0

x^2-81 = 0

DELTA = 0^2-(-81*1*4)

DELTA = 324

DELTA > 0

x = (324^(1/2)+0)/(1*2) or x = (0-324^(1/2))/(1*2)

x = 9 or x = -9

x in { -9, 9} 

x in { -9, 9 }
