A) \[(1,\,6,\,2,\,5)\]
B) (1, 2, 7, 5)
C) (1, 2, -7, 5)
D) (-1, -2, 7, -5)
Correct Answer: C
Solution :
\[\left[ \begin{matrix} 2 & -3 \\ 4 & 0 \\ \end{matrix} \right]-\left[ \begin{matrix} a & c \\ b & d \\ \end{matrix} \right]=\left[ \begin{matrix} 1 & 4 \\ 2 & -5 \\ \end{matrix} \right]\] Þ \[\left[ \begin{matrix} a & c \\ b & d \\ \end{matrix} \right]=\left[ \begin{matrix} 2 & -3 \\ 4 & 0 \\ \end{matrix} \right]-\left[ \begin{matrix} 1 & 4 \\ 2 & -5 \\ \end{matrix} \right]=\left[ \begin{matrix} 1 & -7 \\ 2 & 5 \\ \end{matrix} \right]\] Þ \[(a,b,c,d)=(1,\,\,2,\,\,-7,\,\,5)\].
