8. Write out the form of the partial fraction expansion for the following transfer function. SOME FACTORING AND CANCELING MAY BE REQUIRED IF THE DENOMINATOR IS NOT IRREDUCIBLE G(8) = +4+36 +4+6 To get full credit you need to have the denominators correct and the form of the numer- ators correct. DO NOT solve for the values of the numerator coefficients. You don't need to for credit and it would take a long time.
