Question
यदि $\left[ {\begin{array}{*{20}{c}}2&{ - 3}\\4&0\end{array}} \right] - \left[ {\begin{array}{*{20}{c}}a&c\\b&d\end{array}} \right] = \left[ {\begin{array}{*{20}{c}}1&4\\2&{ - 5}\end{array}} \right]$, तो $(a,b,c,d) = $
$\Rightarrow$ $\left[ {\begin{array}{*{20}{c}}a&c\\b&d\end{array}} \right] = \left[ {\begin{array}{*{20}{c}}2&{ - 3}\\4&0\end{array}} \right] - \left[ {\begin{array}{*{20}{c}}1&4\\2&{ - 5}\end{array}} \right] = \left[ {\begin{array}{*{20}{c}}1&{ - 7}\\2&5\end{array}} \right]$
$\Rightarrow$ $(a,b,c,d) = (1,\,\,2,\,\, - 7,\,\,5)$.
