Vertical asymptotes, occur when the rational is undefined, and that happens when the denominator turns to 0, for this specific case, is when $\bf \cfrac{x-4}{x^2+13x+36}\implies \cfrac{x-4}{0}\impliedby un de fined$

when does that happen? well, it happens at

$\bf x^2+13x+36=0\implies (x+4)(x+9)=0\implies x=
\begin{cases}
-4\\
-9
\end{cases}$
