If you see duplicate rows. and actually if you see duplicate columns-- I will leave that for you to think about-- if you see duplicate rows or duplicate columns, or even if you just see that some rows are linear combinations of other rows-- and I'm not showing that to you right here-- then you know that your determinant is going to be equal to 0.

And that really shouldn't be a surprise. Because if you have duplicate rows, remember what we learned a long time ago. We learned that a matrix is an invertible if and only if the reduced row echelon form is the identity matrix.
So we know that duplicate rows could never get reduced row echelon form to be the identity.
