Using the Routh-Hurwitz Criterion, test the stability conditions of the following closed-loop systems.?

Using the Routh-Hurwitz Criterion, test the stability conditions of the following closed-loop systems in (a), (b), and (c) indicating how many poles in the RHP, LHP, and on the jω-axis? These are the equations within each of those closed loop sytems. a. 3/(S(S+1)(S+2)) b. 7/ ( S(S+1)(S+2)) c.... show more Using the Routh-Hurwitz Criterion, test the stability conditions of the following closed-loop systems in (a), (b), and (c) indicating how many poles in the RHP, LHP, and on the jω-axis?

These are the equations within each of those closed loop sytems.

a. 3/(S(S+1)(S+2))

b. 7/ ( S(S+1)(S+2))

c. 1000/((S+2)(S+3)(S+5))
