SUMMARY
The discussion confirms that if λ is an eigenvalue of matrix A, then λ² is an eigenvalue of matrix A². The proof is established by starting with the eigenvalue equation Ax = λx and manipulating it to show that A²x = λ²x. This demonstrates the relationship between the eigenvalues of A and A² definitively, confirming the mathematical property of eigenvalues under matrix squaring.
