9 is the extraneous solution to the equation x + 3 = 0. Is it true?

Question

x + 3 = 0

x = - 3

3 is the valuable solution.

Can i solve the original equation to find the extraneous solution?

(x - 9)(x + 3) = 0(x - 9)    [Multiply by )x - 9) on each side.]

x = 9, - 3

9 is the extraneous solutionIn this way, i can get number of extraneous solutions..is it true?
