Homework Help: Laplace transform using properties

  1. Dec 20, 2011 #1
    1. The problem statement, all variables and given/known data
    Find the laplace transform of

    3. The attempt at a solution

    The answer I got was [itex]\frac{e[itex]^{-5(s+17)}[/itex]}{(s+17)^{2}}[/itex].
    I thought I finally understood the process, but when I plugged it into wolfram alpha, the answer I got was different...


    Shouldn't the "s" in the exponent be "s+17" or is my understanding really wrong??
