Minor of aij is defined as what?
ADeterminant left after deleting row i and column j
BSum of the remaining entries of the matrix
CDeterminant of the matrix with aij set to zero
DProduct of aij with the sign (-1)^(i+j)
Answer & Solution
Correct answer: A. Determinant left after deleting row i and column j
Striking out the row and column that contain aij leaves a smaller determinant, which is its minor.
