Best ResponseYou've already chosen the best response.0\(\large \frac{s}{5}\frac{5}{(s^2+9)(s^2+4)}= \quad \frac{s}{5}\frac{(s^2+9)(s^2+4)}{(s^2+9)(s^2+4)}\) now just separate denominator. got it ?

Best ResponseYou've already chosen the best response.0don't include s. lets just do partial fraction for 1/(s^2+4)(s^2+9) after that we multiply s to both terms
