Solution for (3x-x^2)/(x^2-9) equation: 


D( x )

x^2-9 = 0

x^2-9 = 0

x^2-9 = 0

1*x^2 = 9 // : 1

x^2 = 9

x^2 = 9 // ^ 1/2

abs(x) = 3

x = 3 or x = -3

x in (-oo:-3) U (-3:3) U (3:+oo)

(3*x-x^2)/(x^2-9) = 0

3*x-x^2 = 0

x*(3-x) = 0

3-x = 0 // - 3

-x = -3 // * -1

x = 3

x*(x-3) = 0

(x*(x-3))/(x^2-9) = 0

( x-3 )

x-3 = 0 // + 3

x = 3

( x )

x = 0

x in { 3} 

x = 0
