Web17 sep. 2024 · We compute the determinant by expanding cofactors along the third column: f(λ) = det (A − λI3) = det (− λ 6 8 1 2 − λ 0 0 1 2 − λ) = 8(1 4 − 0 ⋅ − λ) − λ(λ2 − 6 ⋅ 1 2) = … Web16 sep. 2024 · Now, we can find det (D) by expanding along the first column as follows. You can see that there will be only one non zero term. det (D) = 1 det [ 0 − 1 − 1 − 8 − 4 1 10 − 8 − 4] + 0 + 0 + 0 Expanding again along the first column, we have det (D) = 1(0 + 8 det [− 1 − 1 − 8 − 4] + 10 det [− 1 − 1 − 4 1]) = − 82
