More precisely, the cofactor expansion allows you to express the determinant of size n as a weighted sum of minors. Recall that a minor is the determinant of some (n − 1) × (n − 1) submatrix of the initial matrix. How to find determinants by cofactor expansion? Let A be an n...
To find minors and cofactors, you have to: To find the(i, j)-th minor, cross out thei-th row andj-th column of your matrix and compute the determinant of the remaining matrix. To compute the(i, j)-th cofactor, multiply the(i, j)-th minor by the sign factor(-1)i+j. ...

In fact, one needs to apply the full Laplace expansion method to obtain the determinant of each interim 3 × 3 matrix. This reasoning can be extended to any matrix with m > 3 and it should be clear that more and more layers of interim matrices and determinants are needed as m increases...
