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

$$\frac{2e^3}{((s^2)-6s+9)*s^3}$$

you can factorize the denominator into s,s,s,(s-3),(s-3)

that gives you 5 residuals.

the first 3 should all be the same value but that's apparently not correct, so where

am I going wrong?

Hi Ry122!
Your denominators need to be s s2 s3 s-3 and (s-3)2
