To find the adjoint of the matrix \( A = \begin{pmatrix} 1 & -2 & -3 \\ 0 & 1 & 0 \\ -4 & 1 & 0 \end{pmatrix} \), we will follow these steps: ### Step 1: Find the Minors We need to calculate the minors for each element of the matrix \( A \). The minor \( M_{ij} \) is the determinant of the submatrix formed by deleting the \( i \)-th row and \( j \)-th column. 1. **Minor \( M_{11} \)**: \[ M_{11} = \begin{vmatrix} 1 & 0 \\ 1 & 0 \end{vmatrix} = (1)(0) - (0)(1) = 0 ...
