![### Problem Statement
Use undetermined coefficients to find the particular solution to the following differential equation:
\[y'' + 3y' + 2y = 4e^{-2t}\]
\[Y(t) = \]
### Explanation
In this problem, we are given a second-order non-homogeneous linear differential equation. To solve this, we will use the method of undetermined coefficients to find a particular solution of the form \(Y(t)\).
Analyzing the right-hand side of the differential equation, \(4e^{-2t}\), suggests trying a solution of the form:
\[Y_p(t) = Ae^{-2t}\]
where \(A\) is a coefficient to be determined. Substituting \(Y_p(t)\) into the given differential equation and solving for \(A\) will give us the particular solution.](https://content.bartleby.com/qna-images/question/c700bc18-61e4-4e04-a31d-52f10b21c2d0/424bb6e0-2c0d-4020-8ecc-06bb849e2c86/diigqb_processed.jpeg)
