Chapter 2.6, Problem 1P

Explanation of Solution

Verification:

Consider the following matrix,

A=[1    2    34    5    67    8    9]

The second-row cofactors are given below:

A21=[2    38    9]

Therefore, we get

det(A21)=1824             =6

Now, we have

A22=[1    37    9]

Therefore,

det(A22)=921             =12

We have

A23=[1    27    8]

Therefore,

det(A23)=814             =6

Therefore, the expansion is ,

det(A)=(1)2+1a21det(A21)+(1)2+2a22det(A22)+(1)2+3a23det(A23)             

Substituting the values, we get

det(A)=(4)(6)+5(12)6(6)
