Find the Minors of 3x3 Matrix | Linear Algebra Exercises

We go over how to find all the minors of a 3x3 matrix. This involves eliminating the row and column of the entry corresponding to the minor and then finding the determinant of the remaining submatrix. After finding all minors of the matrix we'll compute the determinant using the cofactor expansion. #linearalgebra
