Surely you mean "inverse Laplace transform"? Assuming you mean $\displaystyle F(s)= \frac{s- 1}{s^2+ s+ 1}$, start by completing the square in the denominator to get a form you can look up in a table of transforms. There is probably one in your text book but there is one here: http://tutorial.math.lamar.edu/pdf/Laplace_Table.pdf.

I think you will need numbers "7" and "8" in that table.
