SUMMARY
The discussion centers on the confusion surrounding the calculation of eigenvalues and eigenvectors, specifically regarding the eigenvalue of 3 and the eigenvector of (1, 1). Participants clarify that the characteristic equation λ² - 4λ + 3 = (λ - 1)(λ - 3) was incorrectly factored, leading to misunderstandings. The correct identification of eigenvalues is emphasized, noting that multiple eigenvalues can exist, as indicated by the phrase "an eigenvalue" in the problem statement. The conversation highlights the importance of careful reading and accurate factoring in solving eigenvalue problems.
