CharacteristicPolynomial[{m, a}, x]
gives the generalized characteristic polynomial with respect to a.

MORE INFORMATION

m must be a square matrix.

It can contain numeric or symbolic entries.

CharacteristicPolyonomial[m, x] is essentially equivalent to Det[m-id x] where id is the identity matrix of appropriate size. »

CharacteristicPolynomial[{m, a}, x] is essentially Det[m-a x]. »
