Evaluate the determinant Evaluate the determinant 6 6 6 2 6

Evaluate the determinant.

Evaluate the determinant |6 6 6 2 6 2 3 3 2|

Solution

determinant =6((6*2)-(2*3)) -2((6*2)-(6*3)) +3((6*2)-(6*6))

determinant =6((12)-(6)) -2((12)-(18)) +3((12)-(36))

determinant =6(12) -2(-6) +3(-24)

determinant =72+12-72

determinant =12
