**Apply the Theorem:**

Use the theorem \(\mathcal{L}(f \star g) = \mathcal{L}(f)\mathcal{L}(g)\) to find the inverse Laplace transform. Also, perform the procedure in another way if indicated.

**(a)** \(\frac{1}{s(s-3)}\) 
- Additionally, use partial fractions and the theorem \(\mathcal{L}^{-1}\left(\frac{F(s)}{s}\right) = \int_{0}^{t} f(\tau) d\tau\).

**(b)** \(\frac{1}{(s^2+9)^2}\)
