Question
**Matrix Inversion using the Gauss-Jordan Method** **Objective:** Use the Gauss-Jordan method to find the inverse of the given matrix (if it exists). If an answer does not exist, enter "DNE" in any cell of the matrix. **Given Matrix:** \[ \begin{bmatrix} 3 & 2 & 0 \\ -2 & 2 & 1 \\ -1 & -1 & 0 \\ \end{bmatrix} \] **Instructions:** 1. **Augment the original matrix** by appending the identity matrix of the same size. 2. **Perform row operations** to convert the left half of the augmented matrix into the identity matrix. 3. The right half of the augmented matrix will then become the inverse of the original matrix if an inverse exists. 4. If you encounter a scenario where a row reduces to all zeros on the left half, the matrix does not have an inverse, and you should enter "DNE" in any cell of the matrix. **Output Matrix (empty for completion):** \[ \begin{bmatrix} \_\_ & \_\_ & \_\_ \\ \_\_ & \_\_ & \_\_ \\ \_\_ & \_\_ & \_\_ \\ \end{bmatrix} \] **Graphs or Diagrams:** The illustration contains a 3x3 matrix setup with empty slots for the inverse matrix, which is to be filled either with numeric values upon completion of the Gauss-Jordan process or "DNE" if the inverse is not possible.
