## Homework Statement

we have 4/((s^2) + 4)(s-1)(s+3)

## Homework Equations

## The Attempt at a Solution

dividing it up do we get:

A/((s^2) + 4) + B/(s-1) + C/(s+3) = 4

or is it

(As + B)/((s^2) + 4) + C/(s-1) + D/(s+3) = 4

The second one. Since the denominator s^{2}+ 4 is quadratic the numerator may be As+ B.
