The Cartesian product `A xxA ` has 9 elements among which are found `(-1, 0) " and " (0, 1)`. Find the set `A` and the remaining elements of `A xxA`.

Explanation

To solve the problem, we need to find the set \( A \) and the remaining elements of the Cartesian product \( A \times A \) given that it has 9 elements, including the pairs \((-1, 0)\) and \((0, 1)\).

### Step 1: Determine the elements of set \( A \)

Given the two pairs \((-1, 0)\) and \((0, 1)\), we can deduce the elements of set \( A \).

From the pair \((-1, 0)\):
- The first element is \(-1\)
