Use the Laplace transform to solve the following initial value problem: y" + 6y +9y=0 y(0)= 4, y/(0)=-3 a. Using Y for the Laplace transform of y(t), i.e., Y = {y(t)}, find the equation you get by taking the Laplace transform of the differential equation =0 b. Solve for Y(s) c. write the above answer in its partial fraction decomposition, Y(s) = + (sta) sta Y(s) = 0+0 d. Now, by inverting the transform, find y(t) =
