For getting the inverse of the given matrix A by row elementary operations we may write the given matrix as

So, the inverse of A is


Since, second row of the matrix A on LHS is containing all zeroes, so we can say that inverse of matrix A does not exist.


Hence, is the inverse of given matrix A.
