Explanation of Solution
Given information:
The following matrix:
Formula used:
Inverse of a
when
Calculation:
For the given matrix, apply the formula for inverse of a
Because this quantity is not zero, the inverse is formed by interchanging the entries on the main diagonal, changing the signs of the other two entries, and multiplying by scalar
Hence, the inverse of the given matrix is-
