What is the inverse of matrix A?

A=

(1) (2) (1)

(2) (-1) (2)

(1) (2) (1)

2. Relevant equations

3. The attempt at a solution

The determinant works out to be 0

The inverse is 1/determinant x adj(A)

Therefore the inverse is 1/0 x adj(A)

So is the answer to, what is the inverse, simply that it is undefined?
