Question: Question 3 Consider the matrix 0 A = UI N O Evaluate the determinant by expanding along column 2. det(A) = x det + x

Question 3 Consider the matrix 0 A = UI N O Evaluate the determinant by expanding along column 2. det(A) = x det + x det + x det X X + X Hence, det(A) (mod 11) = Note: If the coefficient of any sub-matrix determinant is zero, you will still need to include the submatrix in the first line of working and include its determinant in the second line of working
