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


RESOLVENDO

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 = \( \left[\begin{array}{ccc}3&-1&5\\3&7&22\end{array}\right] \)
