Let A be a 3 x 3 matrix satisfying the equation [tex]A^{2}[/tex]-3A-2I=0 where I is the 3x3 identity matrix. Find det(A) given the det(A-3)=2
The Attempt at a Solution
Well can't find anything like this in my textbook, notes or google. I imagine its a pretty simple matrix property I've overlooked but otherwise i have no clue what to do!
Help much appreciated,
