Chapter 11: Q. 12 (page 755)

Use the following matrices to evaluate the given expression.
$A = [\begin{matrix} 0 & 3 & - 5 \\ 1 & 2 & 6 \end{matrix}], B = [\begin{matrix} 4 & 1 & 0 \\ - 2 & 3 & - 2 \end{matrix}], C = [\begin{matrix} 4 & 1 \\ 6 & 2 \\ - 2 & 3 \end{matrix}]$
$- 3 B$

Short Answer

Expert verified

- $- 3 B = [\begin{matrix} - 12 & - 3 & 0 \\ 6 & - 9 & 6 \end{matrix}]$

Step by step solution

Step 1. Given Information

$A = [\begin{matrix} 0 & 3 & - 5 \\ 1 & 2 & 6 \end{matrix}], B = [\begin{matrix} 4 & 1 & 0 \\ - 2 & 3 & - 2 \end{matrix}], C = [\begin{matrix} 4 & 1 \\ 6 & 2 \\ - 2 & 3 \end{matrix}]$

Step 2. Calculation

$- 3 B = - 3 [\begin{matrix} 4 & 1 & 0 \\ - 2 & 3 & - 2 \end{matrix}] = [\begin{matrix} - 12 & - 3 & 0 \\ 6 & - 9 & 6 \end{matrix}]$
