    Here is the question for those who don't want to risk infection or are lazy to download and open:
    y''+6y'+13y = 0, y(0) = 3, y'(0) = 7.

    Well, you start by applying the Laplace transform to both the LHS and RHS. What is Laplace transform of y'', y' ? Express it in terms of L(y) and then throw all the other terms to the RHS, and find the inverse Laplace transform of RHS. Then plug in the initial value conditions.
