Homework Statement



Solve the following:

$$\mathscr{L}_s^{-1} \left\{ \frac{s}{s^2-s+\frac{17}{4}} \right\}$$

Homework Equations



Table of Laplace Transforms.

The Attempt at a Solution



The solution is
$$f(t) = (1/4 )e^{t/2} (\sin(2 t)+4 \cos(2 t))$$

I know I need to break up ##F(s)## into more common Laplace transforms, but I'm not quite sure how to begin.

Hint: Begin by completing the square in the denominator.
