= Homework: Section 3.1 Question 1, 3.1.1 Part 2 of 2 20 4 3 4 3 05-2 Compute the determinant using a cofactor expansion across the first row. Also compute the determinant by a cofactor expansion down the second column. *** HW Score: 90.28%, 8.13 of 9 points Points: 0.5 of 1 (Simply your answer.) OA. Using this expansion, the determinant is -(2)(-23) + (0)(-6)-(4)(15) = B. Using this expansion, the determinant is (2)(-23)-(0)(-6) + (4)(15) = 14. OC. Using this expansion, the determinant is (0)(-6)-(4)(-4) + (5)(-6)= OD. Using this expansion, the determinant is -(0)(-6) + (4)(-4) - (5)(- 6) = Save 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.) OA. Using this expansion, the determinant is (2)(-23) - (0)(-6) + (4)(15)= O B. Using this expansion, the determinant is (0)(-6)-(4)(-4) + (5)(-6)= O C. Using this expansion, the determinant is -(2)(-23) + (0)(-6)-(4)(15) = O D. Using this expansion, the determinant is -(0)(-6) + (4)(-4)-(5)(- 6) =
Determine the value of the third term in the cofactor expansion. Substitute the value for a31 and complete the matrix for C31 below. 49-0488 a31 C31 = (det
Complete the cofactor expansion to compute the determinant. det A =
