Correct Answer : Option (B) : -2, (-1, -2)
Explanation : The zeroes can be calculated by equating the numerator to zero:
5 (s + 2) = 0
5s + 10 = 0
5s = -10
s = -2
The poles can be calculated by equating the denominator to zero:
s^2 + 3s + 2 = 0
s^2 + 2s + s + 2 = 0
s (s + 2) + 1 (s + 2) = 0
(s + 1) (s + 2) = 0
s = -1, -2
