**Problem:**

For the following ODE, find the general solution, \( y = y_c + y_p \), using methods from Chapter 8 Section 5 (Second Order ODEs with 0 RHS) for the complementary solution, \( y_c \), and methods reviewed in class from Chapter 8 Section 6 for the particular solution, \( y_p \):

\[
y'' - 9y = 12 \quad \text{(2.1)}
\]

### Explanation:

The task is to solve the ordinary differential equation (ODE) provided. To find the general solution, break it into two parts:
- **Complementary Solution (\( y_c \))**: This solves the homogeneous part of the ODE where the right-hand side (RHS) is zero.
- **Particular Solution (\( y_p \))**: This addresses the non-homogeneous part due to the RHS being 12.

To achieve this:
1. Use the methods from Chapter 8 Section 5 to determine \( y_c \).
2. Use the approaches discussed in Chapter 8 Section 6 to find \( y_p \).

### Notes:
- \( y'' \) denotes the second derivative of \( y \).
- The ODE is a second-order linear differential equation with constant coefficients.
