To find the eigenvalues you have to find a characteristic polynomial P which you then have to set equal to zero. So in this case P is equal to (λ-5) (λ+1). Set this to zero and solve for λ. So you get λ-5=0 which gives λ=5 and λ+1=0 which gives λ= -1. 1 comment.

WebThe equation A x = λ x characterizes the eigenvalues and associated eigenvectors of any matrix A. If A = I, this equation becomes x = λ x. Since x ≠ 0, this equation implies λ = 1; then, from x = 1 x, every (nonzero) vector is an eigenvector of I. Remember the definition: x is an eigenvector of a matrix A if A x is a scalar multiple of x and x ≠ 0.
