Question 4:

Find the minor of the following matrix. Here is the minor of matrix question4

 
1 1 -1
2 -3 4
3 -2 3
 


Solution:

minor of 1

=
-3 4
-2 3

   = [-9-(-8)]

   = (-9+8)

   = -1

minor of 1

=
2 4
3 3

   = [6-12]

   = (-6)

   = -6

minor of -1

=
2 -3
3 -2

   = [-4-(-9)]

   = (-4+9)

   = 5

minor of 2

=
1 -1
