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

3. The attempt at a solution

Well cant 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,

Ben
