The Tutor and Student worked on solving quadratic equations without a constant term, demonstrating the factoring process. They then progressed to finding the eigenvalues of a 3x3 matrix, which involved calculating its determinant to derive a cubic characteristic equation, followed by using polynomial long division and factorization to find its roots. The Tutor was advised to review the solution after class.

The Student and Tutor reviewed the process of finding eigenvalues for 2x2 matrices. They practiced using the formula `det(A - λI) = 0` to derive quadratic equations, which were then solved using both the quadratic formula and the product sum (middle term split) factorization method. Homework on quadratic equations was planned for further practice.

The Student and Tutor reviewed the process of finding the inverse of a matrix to solve systems of linear equations, practicing calculations for co-factors, adjoints, and determinants. The session then introduced the new academic concept of eigenvalues and eigenvectors, including their fundamental equation and characteristic equation. They worked through a 2x2 matrix example to calculate eigenvalues, and the Student will review this new concept for the next class.
