WebThen the sum in the left hand side of our equality is the cofactor expansion of the matrix B along the j-th row. Thus by the second theorem about determinants this sum is equal to det(B). But B has two equal rows (row i and row j) thus det(B)=0, so the equality holds. Definition. If A is any n by n matrix and C ij is the cofactor of A(i,j) then ...
