    Help Finding Inverse Transform

    I need help with solving this problem,

    F(s) = 1/(s^4 - 81)

    i tried to factor the bottom out and i got it to 1/(s^2+9)(s-3)(s+3) should i just do partial fractions?

    If this is supposed to be an inverse Laplace transform, then yes. If it isn't inverse Laplace then I have no clue....be more specific.
