Eigenvalue of multiplicity 2
WebEigenvector Trick for 2 × 2 Matrices. Let A be a 2 × 2 matrix, and let λ be a (real or complex) eigenvalue. Then. A − λ I 2 = N zw AA O = ⇒ N − w z O isaneigenvectorwitheigenvalue λ , assuming the first row of A − λ I 2 is nonzero. Indeed, since λ is an eigenvalue, we know that A − λ I 2 is not an invertible matrix. WebTo 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 …
