Question

Dada as matrizes A=  | 0 4 -2 |   B=  | -3 6 9 |        C= | 0 -1  0|
                                       | 6 2 8 |           | 12 -6 0|             | 1 -1  2|

Calcule:    2A  - B + 3C

Answer 1

2A= $\left[\begin{array}{ccc}0&8&-4\\12&4&16\end{array}\right]$
3C=$\left[\begin{array}{ccc}0&-3&0\\3&-3&6\end{array}\right]$

2A-B =$\left[\begin{array}{ccc}3&2&5\\0&10&16\end{array}\right]$
$\left[\begin{array}{ccc}3&2&5\\0&10&16\end{array}\right]$ + 3C = $\left[\begin{array}{ccc}3&-1&5\\3&7&22\end{array}\right]$
