Determine those values of λ for which the matrix 1 λ 0 3 2 0 1 2 1 is not invertible
Question
Solution 1
A matrix is not invertible (or singular) if and only if its determinant is zero. So, we need to find the values of λ that make the determinant of the matrix zero.
The matrix is:
1 λ 0 3 2 0 1 2 1
