Consider the following polynomial:
P(s) = (s + 2)(s - 10)(s + 4)(s - 2)
a) Use MATLAB to multiply these terms in order to form a 4th order polynomial.
b) Apply the 'roots' function to your answer in part a to verify your calculation was correct.
c) Use MATLAB to divide your polynomial answer in part a by the term (s + 2).
d) Apply 'roots' to your answer in part c to verify your calculation was correct.
