Let A be a square matrix, then, the solution of characteristic equation |A-kI|=0 is equal to -

Options :
  1. Product of Eigen values of A
  2. Eigen values of A-kI
  3. Product of Eigen values of A-kI
  4. None of the above
Answer and Explanation :-

Answer: Option 1


1) |A| is itself a solution of this characteristic equation which otherwise gives eigen values of A 2) Product of eigen values of A = |A|
