WebFor the eigenvalues of A to be 0, 3 and −3, the characteristic polynomial p (t) must have roots at t = 0, 3, −3. This implies p (t) = –t (t − 3) (t + 3) =–t (t 2 − 9) = –t 3 + 9t Therefore, −t 3 + (11 − 2a) t + 4 − 4a = −t 3 + 9t. For this equation to hold, the constant terms on the left and right-hand sides of the above equation must be equal. WebJun 16, 2024 · A = [3 0 0 3] A has an eigenvalue 3 of multiplicity 2.
