The characteristic root of the matrix are
1,3,6
1,2,4
4,5,6
2,4,6
Then sum of the products of the elements of any row of a determinant A with the co-factors of the corresponding elements is equal to
1
0
|A|
^{1}/_{2 [A]}
skew symmetric matrix
symmetric matrix
diagonal matrix
upper triangular matrix
then B is
2 Δ
3 Δ
6 Δ
, then A^{3} - 4 A^{2} + 3 A + I =
3 I
I
-I
-2 I
14
None of these
AB does not exist
If A and B are any two matrices that AB = 0 and A is non- singular, then_________________.
B = 0
B is singular
B is non singular
B =A
-2
