Web10 years ago. 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. grasshoppers vs cricketsWebJul 3, 2016 · Eigenvectors remain eigenvectors after multiplication by a scalar (including -1).
