2.10 Using the partial fraction expansion method, determine x(n) for the following: (a) X(z) = (z³ + z2)/[(z - 1)(z 3)] with ROC |z> 3 - (b) X(z) = (z² + 2)/[(z - 1)(z - 3)] with ROC 1<<3 X(z) = (23 - 2z2)/[(z)(z+)] with ROC<\z< == (d) Repeat (c) for ROC |z|> (e) X(z) = (z+1)2/z with ROC 0 < z <% | X(z) = (23+222)/[(z)2(z+)] with ROC |z|> -
