Hi Simon,
Thank you for your answer, I will try the Ansatz and comparison of
coefficients.
To find coefficients a, b, and c I tried to solve a system of three
equations but unfortunately it doesn't work. The system is depicted below:
eq1 = a + b == Rl*Rs*Cc*gm + Rc*Cc + Rl*Cc + Rl*Cl + Rs*Cc + R

Sorry, I was stupid: Your polynomial is of degree 3 in s. Thus,
if a factorisation exists, then it is of the above form.
Anyway: From an Ansatz and comparison of coefficie

Here is the text of the expression:
Cc*Cin*Cl*Rc*Rl*Rs*s^3 + Cc*Cl*Rc*Rl*s^2 + Cc*Cin*Rc*Rs*s^2 +
Cc*Cin*Rl*Rs*s^2 + Cc*Cl*Rl*Rs*s^2 + Cin*Cl*Rl*Rs*s^2 + Cc*Rl*Rs*gm*s +
Cc*Rc*s + Cc*Rl*s + Cl*Rl*s + Cc*Rs*s + Cin*Rs*s + 1

I'd suggest to cut and paste text from the browser/notebook, not making
images.
Retyping your long formula by hand is not fun at all.
