Answer:

1st option

Explanation:

To find the difference of the given matrices, we just need to subtract the corresponding elements of the two matrices as shown below:


\left[\begin{array}{cc}-4&8\\3&12\end{array}\right] -\left[\begin{array}{cc}2&1\\-14&15\end{array}\right] \\\\ \\ =\left[\begin{array}{cc}-4-2&8-1\\3-(-14)&12-15\end{array}\right]\\\\ \\ =\left[\begin{array}{cc}-6&7\\17&-3\end{array}\right]

Thus, 1st option gives the correct answer
