I know this may be a very stupid question, but I would really like to know. Is the determinant and the characteristic polynomial of an equation unique? I did several textbook questions and when I look at the solutions, they end up with completely different answers. Sometimes I am wrong and see my mistake, and at other times I am positive I did the cofactor expansion for a matrix correctly. Thanks in advance.(adsbygoogle = window.adsbygoogle || []).push({});
