A
$\left[ {\begin{array}{*{20}{c}}{11}&{ - 7}\\5&{10}\end{array}} \right]$
✓
$\left[ {\begin{array}{*{20}{c}}{ - 1}&{{\rm{ }}1}\\{ - 1}&{ - 2}\end{array}} \right]$
C
$\left[ {\begin{array}{*{20}{c}}{11}&7\\5&{ - 10}\end{array}} \right]$
D
$\left[ {\begin{array}{*{20}{c}}{12}&{ - 7}\\5&{ - 10}\end{array}} \right]$

✓

Answer

Correct option: B.

$\left[ {\begin{array}{*{20}{c}}{ - 1}&{{\rm{ }}1}\\{ - 1}&{ - 2}\end{array}} \right]$

b
(b) $A = \left[ {\begin{array}{*{20}{c}}5&{ - 3}\\2&4\end{array}} \right]$and $B = \left[ {\begin{array}{*{20}{c}}6&{ - 4}\\3&6\end{array}} \right]$,

$\therefore$ $A - B = \left[ {\begin{array}{*{20}{c}}{ - 1}&{\,\,\,1}\\{ - 1}&{ - 2}\end{array}} \right]$.
