Question

Find the characteristic equation and all of the eigenvalues for the matrix A= -2 1 0 | -2 0 1 without using a calculator. Show your work.

Answer 1

We can't find the eigenvalues and characteristic equations of matrix A.

Explanation:

Here,

`A=\left[\begin{array}{ccc}-2&1&0\\-2&0&1\end{array}\right]`

it is a 2 × 3 matrix, which is not a square matrix.

So, we are unable to find the eigenvalues and characteristic equations of matrix A.
