Cofactor Cofactor of A Matrix, Formula (With Solved Example)

Web$A^2 + A + I$ is invertible (with inverse $I - A$), and $A^2$ is nilpotent (as $(A^2)^2 = A(A^3) = 0$), and the sum of a unit with a commuting nilpotent is again a unit. Indeed, $((A^2 + A + I) + A^2)(I - A) = I + (I - A)A^2 = I + A^2$, which has inverse $I - A^2$, so $(2A^2 + A + I)^{-1} = (I - A)(I - A^2) = I - A - A^2$. WebMinors 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. Below is a detailed explanation on “what are ...
