    1. The problem statement, all variables and given/known data

    this is the last step to a laplace transform, but i'm stuck..
    [tex]\frac{(3-2x)}{((s+3)2)+4}[/tex]
    to
    -2[tex]\frac{(s+3)}{(((s+3)2)+4)}[/tex]9/2 [tex]\frac{2}{((s+3)2)+4}[/tex]


    thanks

    Hi myusernameis! :smile:

    (use ^ not SUP in LaTeX :wink:)

    [tex]\frac{(3-2s)}{((s+3)^2)+4}[/tex]

    = [tex]\frac{(9 - 6 - 2s)}{((s+3)^2)+4}[/tex]

    = -2[tex]\frac{(s+3)}{(((s+3)^2+4)}[/tex] + 9/2 [tex]\frac{2}{((s+3)^2)+4}[/tex] :wink:
