Solve the initial value problem by laplace transforms:

y" - 4y' - 5y = 2 + e^(-t); y(0) = y'(0) = 0.

I have the first couple steps done, but I keep getting stuck, so if someone would help me with this problem I would appreciate it. It is on the review for my final and I think there will be one like it on the test, so if you could go into detailed explaination and show every step, maybe I will be able to do the problem on the final. Thank you.
