Match the cofactors to their corresponding entries in the matrix.

The co-factors and their values are shown in the table below.

Step-by-step explanation:

We are given the matrix, .

It is required to match the co-factors with the corresponding values.

As, the co-factors are given by,

= , where the d= determinant of the matrix after removing the i- row and j- column.

So, we have,

1. .

So,

i.e.

2. .

So,

i.e.

3. .

So,

i.e.

4. .

So,

i.e.

5. .

So,

i.e.

Thus, we get,

Co-factor                 Value

                             16

                            27

                            -2

                           -5

                          -22
