Calculate matrix determinant with step-by-step algebra ... The product of a minor and the number + 1 or - l is called a cofactor. COFACTOR Let M ij be the minor for element au in an n x n ... The sum of these products gives the value of the determinant.The process of forming this sum of products is called expansion by a given row ...
To do so, we add the first row to the second row, and we subtract the first row multiplied by 2 from the fourth row: Once we have transformed to 0 all the elements except one of the chosen column, we compute the determinant of the 4×4 matrix using cofactor expansion.

The cofactor expansion is a method to find determinants which consists in adding the products of the elements of a column by their respective cofactors. Being the i, j cofactor of the matrix defined by: Where M ij is the i, j minor of the matrix, that is, the determinant that results from deleting the i-th row and the j-th column of the matrix.
