Let A, B E Rnxn and let R[x] be the set of all polynomials in variable x with coefficients in R. Definition 1: For any p(x) = 0 C₂x² € R[x] define the "evaluation of p(x) at A" as vi=0 p(A) := k Σ c₁A¹ = c₂A¹ + Ck−1A² i=0 ++C₁A+ coIn, (here Aº = In). = Definition 2: Two matrices A, B E Rnxn are said to commute if AB = BA. Let A, B € Rnxn be similar. Show that for any polynomial p(x) = R[x] that p(A) and p(B) are similar. Specifically, show that if B = Q-¹AQ, then p(B) = Q¯¹p(A)Q. (
