1.	Find inverse of a matrix 1 2 1[ 3 0 1 ]0 2 1using adjoint method.
Answer» Step-by-step explanation: Conclusion The INVERSE of A is A-1 only when A × A-1 = A-1 × A = I. To find the inverse of a 2X2 matrix: swap the positions of a and d, put NEGATIVES in front of b and c, and DIVIDE everything by the determinant (ad-bc). SOMETIMES there is no inverse at all.

Conclusion

The INVERSE of A is A-1 only when A × A-1 = A-1 × A = I.

To find the inverse of a 2X2 matrix: swap the positions of a and d, put NEGATIVES in front of b and c, and DIVIDE everything by the determinant (ad-bc).

SOMETIMES there is no inverse at all.
