Thanks for replying. Yes they are real constants. Do you have a link to an example similar to this. This is my first math class since I took calculus over 10 years ago. I'm looking as to what the "A" "B" etc. are.
For a non-factorable quadratic denominator, just start with a*s + b in the first numerator and c*s + d in the second. These are just non-constant linear factors.
