For what real values of a is the expression (a + 3)/((a^2 - 4)(a + 3)) undefined? List your answers in increasing order separated by commas.

\(\frac{a+3}{(a^2 - 4)(a+3)} = \frac{1}{a^2 - 4} \quad (a \neq -3)\)

 

\(\boxed{a \neq -3, -2, 2}\)

 

^^the expression is undefined for these values of a.
