1.4.3 Matrix transformations

Condition: Matrices are given. \[ \begin{aligned} A & =\left(\begin{array}{ccc} 2 & 4 & 3 \\ 6 & -8 & 2 \\ -2 & 2 & 6 \end{array}\right), K=\left(\begin{array}{ccc} 5 & 6 & 0 \\ 2 & -3 & 5 \\ 1 & 4 & -7 \end{array}\right) \\ C & =\left(\begin{array}{ccc} 2 & 0 & 2 \\ 0 & -1 & -3 \\ 3 & 4 & 1 \end{array}\right) . \end{aligned} \] Compute \( A(2 C-4 K) \).
