![**Title: Solving a System Using the Method of Undetermined Coefficients**
**Objective:** Use the method of undetermined coefficients to find a general solution to the given system of differential equations.
**System Description:**
The system is defined by the differential equation:
\[ \mathbf{x}'(t) = A\mathbf{x}(t) + \mathbf{f}(t) \]
Where:
- **Matrix \( A \):**
\[
A = \begin{bmatrix}
6 & 1 \\
5 & 2
\end{bmatrix}
\]
- **Function \( \mathbf{f}(t) \):**
\[
\mathbf{f}(t) = \begin{bmatrix}
-13 \\
-5
\end{bmatrix}
\]
**Methodology:**
The method of undetermined coefficients seeks a particular solution to the non-homogeneous differential equation by proposing a form for this solution and determining the coefficients that satisfy the equation.
**Steps to Solve:**
1. **Calculate the homogeneous solution**: Solve the associated homogeneous system \(\mathbf{x}'(t) = A\mathbf{x}(t)\).
2. **Select the form of the particular solution**: Based on \(\mathbf{f}(t)\), propose a form for the particular solution \(\mathbf{x}_p(t)\).
3. **Determine coefficients**: Substitute \(\mathbf{x}_p(t)\) into the system to find values for the undetermined coefficients.
4. **General Solution**: Combine the homogeneous and particular solutions to express the general solution as:
\[ \mathbf{x}(t) = \mathbf{x}_h(t) + \mathbf{x}_p(t) \]
**Conclusion:**
Utilize linear algebra and differential equations techniques to evaluate \(\mathbf{x}'(t)\), ensuring all parts satisfy the original system, and derive a complete general solution.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Ff26bd2c7-a69a-414f-95bc-e32ed97937d0%2Fa0e8d370-93e2-4c4b-9133-5d4845fde72d%2Fclhvcs9_processed.png&w=3840&q=75)
