Evaluate the determinant for the following matrix: [3 3 1} {-2 0 -2} {-2 4 -3}A. -36B. 12C. 10D. -42
Accepted Solution
A:
Step-by-step answer:determinant of 3 3 1-2 0 -2-2 4 -3expand by second row, note the sign of cofactors-[-2(3*(-3)-4*1)] +[0(3*3-(-2*1))] -[-2(3*4-(-2*3))]=2(-13) + 0 +2(18)=-26+0+36=10
