Question
Compute the determinant using a cofactor expansion across the first row. Also compute the determinant by a cofactor expansion down the second column. 3 -3 4 3 1 3 4 -2 Compute the determinant using a cofactor expansion across the first row. Select the correct choice below and fill in the answer box to complete your choice. (Simplify your answer.) O A. Using this expansion, the determinant is - (3)(-14)+(-3)(-9)- (4)(11)=| O B. Using this expansion, the determinant is (3)(- 14)- (- 3)(-9) + (4)(11)= O C. Using this expansion, the determinant is (- 3)(- 9) – (1)(- 10) + (4)(- 3) = . O D. Using this expansion, the determinant is -(-3)(-9) + (1)(-10)- (4)(- 3) = Compute the determinant using a cofactor expansion down the second column. Select the correct choice below and fill in the answer box to complete your choice. (Simplify your answer.) ts O A. Using this expansion, the determinant is (3)(-14)- (-3)(-9)+ (4)(11) = ni O B. Using this expansion, the determinant is -(-3)(-9)+(1)(-10)- (4)(-3) = O C. Using this expansion, the determinant is - (3)(- 14) + (– 3)(- 9) – (4)(11) =. O D. Using this expansion, the determinant is (- 3)(-9)- (1)(-10)+ (4)(-3) = - M
