Hi, now we are going to find the value of c.
00:04
Now the given augmented matrix is 1 .0, 2, 3, 4 .0, 1, 2, 3, 0, 1, 2, 3, 0, 0, 0, 0, 0, c squared minus 1, c plus 1.
00:28
Now the given condition is this argumented matrix has exactly one parameter.
00:34
So we have rank of a is equal to 2 and rank of ab is also equal to 2.
00:44
So we get c squared minus 1 is equal to 0 and c plus 1 is equal to 0.
00:51
Then we have c squared is equal to 1...
