Answer:

1st option

Step-by-step explanation:

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

[tex]\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][/tex]

Thus, 1st option gives the correct answer

Answer:

The correct answer is first option

| -6   7  |

| 17   3  |

Step-by-step 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
