pls help.. I can't get this right

0 1 -6 Let A = 4 -4 . We can find the determinant of A by using row reduction: 16 -17 4 -4 First we swap the first and second rows to get O 1 -6 4 16 -17 By what factor does this change the determinant? -4 -16 16 Next we multiply the first row by -4 to get 0 1 -6 4 16 -17 -4 -16 16 Next we multiply the first row by -4 to get 0 1 -6 16 17 By what factor does this change the determinant? -4 -16 16 Finally we replace the third row by the sum of itself and the first row to get 0 1 -6 . 0 By what factor does this change the determinant? Since the determinant of the row reduced matrix is the determinant of A is
