Question
**Problem 9**: Find the value of \( a \) so that the function \( g(x) \) is continuous at \( x = 0 \) where

\[
g(x) = 
\begin{cases} 
\frac{1}{2x e^{3x}} - \frac{1}{x(x+2)} & \text{if } x \neq 0 \\ 
a & \text{if } x = 0 
\end{cases}
\]

In order to ensure that \( g(x) \) is continuous at \( x = 0 \), the limit of the function as \( x \) approaches 0 from both sides must equal \( g(0) \). Therefore, calculate the limit of \( \frac{1}{2x e^{3x}} - \frac{1}{x(x+2)} \) as \( x \to 0 \) and set it equal to \( a \).
