Question: Consider the equation s3 + 9s2 + (8 + K)s + 2 K = 0 a. Use MATLAB to obtain the value of K required

Consider the equation
s3 + 9s2 + (8 + K)s + 2 K = 0
a. Use MATLAB to obtain the value of K required to put the dominant root at the breakaway point. Obtain the three roots corresponding to this value of K.
b. Investigate the sensitivity of the dominant root when K varies by ± 10% about the value found in part (a).
