I am trying to find the Laplace Inverse of (s+2)/(s-1) I know 1/(s-1) is e^t but what is laplace inverse (s+2)/1 ? or should I not split the denom and numerator up? Thanks

OpenStudy (turingtest):

can't we do some long division here?

OpenStudy (turingtest):

\[\frac{s+2}{s-1}=1+\frac3{s-1}\]

OpenStudy (anonymous):

I did expand and did got (3/(s-1)) + 1 if that is what you meant

OpenStudy (turingtest):

that is the only answer I see, and it will yield the delta function

OpenStudy (turingtest):

I look at it like polynomial long division|dw:1338158620623:dw|
