Question

Different methods to find eigen values for a matrix

Answer 1

we can find the eigenvectors by Gaussian Elimination. to row echelon form, and solve the resulting linear system by back substitution. – We must find vectors x which satisfy (A − λI)x = 0. – First, form the matrix A − 4I: A − 4I =   −3 −3 3 3 −9 3 6 −6 0
