Question
Everything we've done with systems of 2 linear, constant coefficient, homogeneous differential equations works for larger systems as well. Ask wolframalpha.com for the eigenvalues and eigenvectors of the following system of three differential equations, and use the result to write the general solution:

\[
\vec{X}'(t) = \begin{bmatrix} -2 & -4 & 2 \\ -2 & 1 & 2 \\ 4 & 2 & 5 \end{bmatrix} \vec{X}(t)
\]

**Explanation:**

This is a system of three linear homogeneous differential equations represented in matrix form. The matrix shown is:

\[
\begin{bmatrix} -2 & -4 & 2 \\ -2 & 1 & 2 \\ 4 & 2 & 5 \end{bmatrix}
\]

You are tasked with finding the eigenvalues and eigenvectors of this matrix, which are crucial for solving the system of differential equations to find the general solution. This can often be done using computational tools like Wolfram Alpha. The solution involves analyzing the behavior of the system over time \( t \) by understanding the properties of this matrix.
