1. The problem statement, all variables and given/known data find solution using laplace transforms y'' + 4y = 8 alright, so i did the laplace transform of both sides and i get (s^2 + 4)L(y) - 11s - 5 = 8/s so i isolate L(y) and i get this expression: L(y) = (11s^2 + 5s + 8)/(s*(s^2 + 4)) however, the textbook says the answer is: L(y) = 2/s + (9s + 5)/(s^2 + 4) And i dont know how to get from my expression to the book's. I'm pretty good at doing inverse laplace transforms, its just that i cant seem to do the algebra right. CAn someone help me see how to get to the right expression for L(y)? thanks!!
