**Question 4**

**Find the general solution of this ODE:**

\[
\frac{d^2y}{dt^2} + 14\frac{dy}{dt} + 45y = 3t^2 - 4 + 2e^{-2t}
\]

The solution will be of the form:

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

so use \( C \) and \( D \) as the arbitrary constants.

**a) The general solution is**

\[
y(t) = \boxed{}
\]
