    Laplace transform problem

    Given: f(0)=0 , f\prime(0)=1

    f\prime\prime + 2f\prime + 5f = t

    After taking laplace on both sides I have got ,

    (s^2 \tilde f(s) -1) + 2(s\tilde f(s)) + 5\tilde f(s) = \frac{1}{s^2}

    How should i proceed from here ?

    Thanks

    Make \tilde f(s) the subject. Then get the inverse.
