![**Title: Solving Differential Equations Using the Method of Undetermined Coefficients**
**Introduction:**
In this exercise, we will find a particular solution to the differential equation using the Method of Undetermined Coefficients.
**Problem Statement:**
Given the differential equation:
\[ x''(t) - 14x'(t) + 49x(t) = 3te^{7t} \]
**Methodology:**
The Method of Undetermined Coefficients is a technique used to find particular solutions to linear differential equations with constant coefficients and specific types of non-homogeneous terms.
**Solution Outline:**
1. **Identify the form of the particular solution**: Based on the right-hand side of the equation \(3te^{7t}\), propose a suitable form for \(x_p(t)\) that might include terms with similar exponential growth and polynomial functions.
2. **Determine undetermined coefficients**: Substitute the proposed solution into the differential equation to determine the unknown coefficients.
3. **Combine with homogeneous solution**: The total solution will include both the particular and homogeneous solutions.
**Solution:**
A solution is given by:
\[ x_p(t) = \, \_\_\_\_ \] (Fill in the particular solution form and coefficients once calculated)
**Summary:**
Once the particular solution \(x_p(t)\) is found, it can be added to any complementary solution of the homogeneous equation to form the general solution to the original problem.
**Conclusion:**
The Method of Undetermined Coefficients offers a structured way to tackle non-homogeneous linear differential equations, especially when the non-homogeneous part matches specific forms.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F799db758-6264-477e-875f-1cfecc426da7%2F4610718c-93d9-43d4-b6bf-84065b088960%2F6pu46cf_processed.png&w=3840&q=75)
