I need help finding the eigenvalues of a 4x4 matrix. Been working with the same problem for 2 days now. I just can't solve it. Help me pls!
The matrix (A) is:
(Notice that the matrix is symmetric, if that is to any help)
I have come this far (If I'm on the right track).
det = 0
How do I solve for L from this? I would appreciate any help.
