WebWe evaluate our 3 × 3 determinant using expansion by minors. This involves multiplying the elements in the first column of the determinant by the cofactors of those elements. We subtract the middle product and add the final product. 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.
