(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

How do I solve the following differential equation with the Laplace Transform:?

f(t)'' - a*f(t) = 0 (all ICs are equal to zero).

2. Relevant equations

3. The attempt at a solution

So, I get something like F(s)*(s^2 - a) = 0. I don't know where to go from there.
