Complete these matrices so that det A = 25. Then check that A = 5 is repeatedthe trace
Chapter 6, Problem 13(choose chapter or problem)
Complete these matrices so that det A = 25. Then check that A = 5 is repeatedthe trace is 10 so the determinant of A - AI is (A - 5)2. Find an eigenvector with Ax = 5x. These matrices will not be diagonalizable because there is no second line of eigenvectors.
