WebInvertible Matrix Theorem) which implies that the homogeneous system has at least one free variable ... Theorem: A scalar λ is an eigenvalue of an n×n matrix A if and only if λ satisfies the characteristic equation det(A−λI) = 0. 2. It can be shown that if A is an n × n matrix, then det(A − λI) is a polynomial in the variable λ of ... WebAssume λ is an eigenvalue of A. Since A is an invertible matrix, D e t ( A) ≠ 0. Since λ is an eigenvalue of A, D e t ( A − λ I 2) = 0. Let A = ( 1 2 3 4) .Thus, D e t ( A) ≠ 0. Then, D e t ( A − λ I 2) = λ 2 − 5 λ − 2 = 0. So, solution of this equation, x 1, x 2 = ± 5 + 4 2 2. Now, … The question is asking whether A is invertible given that it has an eigenvalue …
