Show that λ is an eigenvalue of the B matrix if, and only if λ is an eigenvalue of B'
It's supposed to be really easy to show that but I guess that it is only the case when you know how to do it :P

Let's be clear. Please state what B' is. Notation isn't always uniform.
Is [tex]|\lambda I - B|[/tex] any different from [tex]|\lambda I - B'|[/tex]
Fair enough. Now the answer to my determinant question...
Pick any 2x2 matrix and play with it a bit.
