    I tried extract an s at the denominator and perform complete the square at denominator.But i feel it would be way too long to solve this problem. Gimme guide on how to tackle this problem

    2. Relevant equations

    Do Partial Fraction Decomposition (factor s from the denominator and complete the square for later):
    L{...} = A/s + (Bs+C)/[(s+1)^2+4]
    then "fit" the fractions so you can use the Laplace transform table.
    you are done.

    Good Luck.
