Question

3.12h

Use the given matrices to find the expression.

\[ A = \begin{pmatrix} 3 & 8 & 2 \\ 8 & 9 & 3 \\ 6 & 2 & 8 \end{pmatrix} \quad C = \begin{pmatrix} 9 & 7 & 7 \\ 1 & 8 & 9 \\ 2 & 8 & 7 \end{pmatrix} \]

\[ C - (A + I) \]

\[ C - (A + I) = \begin{pmatrix} \, & \, & \, \\ \, & \, & \, \\ \, & \, & \, \end{pmatrix} \]

Explanation:
- The matrices \(A\) and \(C\) are given as 3x3 matrices.
- The expression requires calculating \(C - (A + I)\), where \(I\) is the identity matrix of the same order as \(A\) and \(C\).
- You are to solve the equation and fill in the resulting matrix.
