WebActually both work. the characteristic polynomial is often defined by mathematicians to be det (I [λ] - A) since it turns out nicer. The equation is Ax = λx. Now you can subtract the λx so you have (A - λI)x = 0. but you can also subtract Ax to get (λI - A)x = 0. You can easily check that both are equivalent. Comment ( 12 votes) Upvote Downvote
