Laplace transform problem

  1. Sep 30, 2011 #1
    in this question x(t) is right sided signal
    so ROC should be to the right of right most pole
    but here they've given ROC is Re(s) >-3
    but there is a pole @ -2

    Yes I also think that the ROC should be Re(s)>-2. Looks like the book has a typo.
