## Solving Second-Order Ordinary Differential Equations (ODE)

## Problem Statement

Find the general solution of the following ordinary differential equation (ODE):

\[ \frac{d^2y}{dt^2} + 2\frac{dy}{dt} + 17y = 11e^{-3t} \]

## Solution Form

The solution will be of the form:

\[ y(t) = C y_1(t) + D y_2(t) + y_p(t) \]

where \( C \) and \( D \) are arbitrary constants.

## General Solution

The general solution to the ODE is given by:

\[ y(t) = \]

(Note: This field is left blank and should be filled out by the student or educator as part of solving the problem.)

## Explanation

- **Homogeneous Solution:** The first step is to solve the related homogeneous ODE (where the right-hand side is zero). This yields the complementary function \( y_c(t) = C y_1(t) + D y_2(t) \).

- **Particular Solution:** Next, solve for the particular solution \( y_p(t) \) that satisfies the non-homogeneous ODE.

- **General Solution:** Combine the homogeneous and particular solutions to find the general solution.

In this case, students should use their knowledge of solving second-order ODEs to find \( y_1(t) \), \( y_2(t) \), and \( y_p(t) \), and then combine them to get the final solution.

### Note:
Make sure to check the conditions and methods appropriate for finding \( y_1(t) \), \( y_2(t) \), and \( y_p(t) \), such as the method of undetermined coefficients, the variation of parameters, or other relevant techniques.
