If \( A = \begin{bmatrix} 2-k & 2 \\ 1 & 3-k \end{bmatrix} \) is a singular matrix, then the value of \( 5k - k^2 \) is equal to:
If \( A = \begin{bmatrix} 2-k & 2 \\ 1 & 3-k \end{bmatrix} \) is a singular matrix, then the value of \( 5k - k^2 \) is equal to:
Show Hint
A \(2 \times 2\) matrix is singular when \(ad - bc = 0\). This condition implies linear dependence between rows or columns.
