![**Solving Differential Equations using the Annihilator Method**
This section will guide you through solving a differential equation using the Annihilator Method. We'll explore the necessary steps with a given example.
**Problem Statement:**
Solve the following differential equation using the Annihilator Method:
\[ y'' + y' - 6y = 2x + 1 - 3e^{2x} \]
with initial conditions:
\[ y(0) = 0 \]
\[ y'(0) = 3 \]
**Understanding the Problem:**
1. **Identify the differential equation:** The given differential equation is a second-order linear differential equation with non-homogeneous terms on the right-hand side (2x + 1 - 3e^{2x}).
2. **Define the initial conditions:** These conditions will be necessary to find the specific solution that satisfies both the general solution of the differential equation and the given initial conditions.
The main steps involved in solving this equation using the annihilator method are:
1. **Find the complementary function (CF) or the solution to the homogeneous equation** \( y'' + y' - 6y = 0 \).
2. **Identify an appropriate annihilator for the non-homogeneous terms** \(2x + 1 - 3e^{2x}\).
3. **Apply the annihilator to both sides of the differential equation to transform it into a homogeneous differential equation**.
4. **Solve for the particular solution (PS) of the original non-homogeneous differential equation**.
5. **Combine the complementary function and a particular solution to get the general solution**.
6. **Use the initial conditions to find the specific solution for the given differential equation**.
By following these steps, you will be able to solve the differential equation provided in the problem statement.
