Extracted text: Q2: Use the Routh stability criterion to determine the number of roots in the left-half plane, the right- half plane, and on the imaginary axis for the given characteristic equation: A(s) = s6 + 3s5 + 5s4 + 9s3 + 8s2 + 6s + 4 = 0 Draw conclusions about the stability of the closed-loop system.
