- $$A = \left[ \begin{array} { r r r } - 9 & 4 & 6 \\- 6 & 3 & - 1 \\- 9 & - 3 & 5\end{array} \right]$$

• A) \(A I _ { n } = \left[ \begin{array} { r r r } - 9 & 4 & 6 \\ - 6 & 3 & - 1 \\ - 9 & - 3 & 5 \end{array} \right] \left[ \begin{array} { l l l } 1 & 0 & 0 \\ 0 & 1 & 0 \\ 0 & 0 & 1 \end{array} \right] = \left[ \begin{array} { r r r } 9 & - 4 & - 6 \\ 6 & - 3 & 1 \\ 9 & 3 & - 5 \end{array} \right]\)
• B) \(A I _ { n } = \left[ \begin{array} { l l l } 1 & 0 & 0 \\ 0 & 1 & 0 \\ 0 & 0 & 1 \end{array} \right] \left[ \begin{array} { r r r } - 9 & 4 & 6 \\ - 6 & 3 & - 1 \\ - 9 & - 3 & 5 \end{array} \right] = \left[ \begin{array} { r r r } - 9 & 4 & 6 \\ - 6 & 3 & - 1 \\ - 9 & - 3 & 5 \end{array} \right]\)
• C) \(A I _ { n } = \left[ \begin{array} { l l l } 1 & 0 & 0 \\ 0 & 1 & 0 \\ 0 & 0 & 1 \end{array} \right] \left[ \begin{array} { r r r } - 9 & 4 & 6 \\ - 6 & 3 & - 1 \\ - 9 & - 3 & 5 \end{array} \right] = \left[ \begin{array} { r r r } 9 & - 4 & - 6 \\ 6 & - 3 & 1 \\ 9 & 3 & - 5 \end{array} \right]\)
• D) \(A I _ { n } = \left[ \begin{array} { r r r } - 9 & 4 & 6 \\ - 6 & 3 & - 1 \\ - 9 & - 3 & 5 \end{array} \right] \left[ \begin{array} { l l l } 1 & 0 & 0 \\ 0 & 1 & 0 \\ 0 & 0 & 1 \end{array} \right] = \left[ \begin{array} { r r r } - 9 & 4 & 6 \\ - 6 & 3 & - 1 \\ - 9 & - 3 & 5 \end{array} \right]\)
