Use either elementary row or column operations, or cofactor expansion, to find the determinant by hand. Then use a software program or a graphing utility to verify your answer. 4 2 1
0 2 0
5 6 1
STEP 1: Expand by cofactors along the second row.
4 2 1
0 2 0 = 2
5 6 1
STEP 2: Find the determinant of the 2 x2 matrix found in Step 1.
STEP 3: Find the determinant of the original matrix.
