Answer 1

The correct answer is first option

| -6 7 |

| 17 3 |

Explanation:

It is given two 2x2 matrices we have to find the difference ,

| -4 8 | - | 2 1 |

| 3 12 | |-14 15 |

To find the difference

| -4 8 | - | 2 1 | = | (-4 -2) (8 - 1) |

| 3 12 | |-14 15 | | (3 - -14) (12 - 15) |

= | -6 7 |

| 17 3 |

Therefore the correct answer is first option

Answer 2

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
