## Homework Statement

d'^2 (y)/dt + 4 (dy/dt) + 4y = -7(e^(-3t)). Here I need to forced response of this differential equation using laplace transform technique.

## Homework Equations

## The Attempt at a Solution

I understand the part of converting each term to each laplace,

d^2y/dt to Y(s)*s^2, dy/dt to Y(s)*s, y(t) to Y(s), where each term is being converted from f(t) to F(s). I really confused on how to proceed with this question form here
