e a 4 x 4 matrix over Csuch that rank (A) = 2 and A= A Let A be a 4 diagonalizable. Then 20. 0. Suppose that A i (0 1 (A) (B) (C) (D) One of the Jordan blocks of the Jordan canonical form of A iso 0 A2 = A # 0 There exist a vector v such that Av 0 but Av = 0 The characteristic polynomial of A is x - x
