Exercises 19–23 concern the polynomial
p(t) = a0 + a1t + … + an−1tn−1 + tn
and an n × n matrix Cp called the companion matrix of p:
Cp =
20. Let p(t) = (t − 2)(t − 3)(t − 4) = −24 + 26t − 9t2 + t3 Write the companion matrix for p(t), and use techniques from Chapter 3 to find its characteristic polynomial.
