Consider the following polynomials
1. s4 + 7s3 + 17s2 + 17s + 6
2. s4 + 11s3 + 41s2 + 61s + 30
3. s4 + s3 + 2s2 + 3s + 2.
Among these polynomials, those which are Hurwitz would include—
-
- 1 and 3
- 2 and 3
- 1 and 2
- 1, 2 and 3
- 1 and 3
Correct Option: C
Since all the coefficients in all the there polynomials are positive, we need to construct Hurwitz table for further checking.
