Question 20. The 3 equations I am using were given to me by my prof, so I can't imagine it being wrong. But you never know. Well as you can see my work is shown. My goal is to find the determinant of this 3 x 3 matrix, and from the determinant find the eigenvalues. Then using those eigenvalues to find the eigenvectors.The problem I run into when doing the determinant and then setting it equal 0 I get: -lamda^3 + 6lamda^2 - 10lamda + 4 = 0. Which I can't really see how to factor. So I can't imagine it having all real roots. And I am pretty sure it should have all real roots.(adsbygoogle = window.adsbygoogle || []).push({});

Thanks for any help.
