Answer:
Minors and Cofactors. Minors and cofactors are two of the most important concepts in matrices as they are crucial in finding the adjoint and the inverse of a matrix. To find the determinants of a large square matrix (like 4×4), it is important to find the minors of that matrix and then the cofactors of that matrix.

Step-by-step explanation:
The knowledge of Minors and Cofactors is compulsory in the computation of adjoint of a matrix and hence in its inverse as well as in the computation of determinant of a square matrix. This technique of computing determinant is known as Cofactor Expansion.
