All ISRO Electrical Engineering (EE) papers | ISRO Electrical Engineering (EE) 2023

The eigen values of the matrix A = [[0, 1, 0], [0, 0, 1], [0, -2, -3]] are

  • A. 0, -1, -2
  • B. 0, -3, -4
  • C. 0, 0, -4
  • D. None of these

Answer: A. 0, -1, -2

Explanation: Characteristic equation det(λI - A) = λ(λ² + 3λ + 2) = λ(λ + 1)(λ + 2) = 0, giving eigenvalues 0, -1, -2.
