Assignment:
Consider the following characteristic equations:
(a) s^3 + 2s^2 + s +2 = 0
(b) s^5 + 2s^4 + 24s^3 + 48s^2 - 25s - 50 = 0
Using Routh stability criterion, determine whether the above systems are stable or unstable.
Provide complete and step by step solution for the question and show calculations and use formulas.
