1) Fill in the missing numbers. \( \left[\begin{array}{cc}2 & 8 \\ -3 & 2 \\ 0 & -9\end{array}\right]-\left[\begin{array}{rr}5 & 6 \\ 5 & 3 \\ 9 & 0\end{array}\right]=\left[\begin{array}{ll}\square \\ \square \\ \square & \square\end{array}\right. \)

To solve the matrix subtraction problem, we'll subtract the corresponding elements of the two matrices. Given: \[ \begin{array}{cc} 2 & 8 \\ -3 & 2 \\ 0 & -9 \end{array} - \begin{array}{cc} 5 & 6 \\ 5 & 3 \\ 9 & 0 \end{array} = \begin{array}{cc} \square & \square \\ \square & \square \\ \square & \square \end{array} \] **Step-by-Step Subtraction:** 1. **First Row:** \[ 2 - 5 = -3 \\ 8 - 6 = 2 \] So, the first row of the result is \([-3 \quad 2]\). 2. **Second Row:** \[ -3 - 5 = -8 \\ 2 - 3 = -1 \] So, the second row of the result is \([-8 \quad -1]\). 3. **Third Row:** \[ 0 - 9 = -9 \\ -9 - 0 = -9 \] So, the third row of the result is \([-9 \quad -9]\). **Final Result:** \[ \begin{array}{cc} -3 & 2 \\ -8 & -1 \\ -9 & -9 \end{array} \] Or, using the matrix notation: \[ \left[\begin{array}{cc} -3 & 2 \\ -8 & -1 \\ -9 & -9 \end{array}\right] \]
