Question

2. Find the inverse of A=(1 2)
(3 4)​

Answer 1

Answer:

The inverse of a 2×2 2 × 2 matrix can be found using the formula 1|A|[d−b−ca] 1 | A | [ d - b - c a ] where |A| is the determinant of A . The determinant of [1234] [ 1 2 3 4 ] is −2 . These are both valid notations for the determinant of a matrix.
