Answer:
Set A = {-1, 0, 1}
Remaining elements of A × A = {(-1, -1), (-1, 1), (0, -1), (0, 0), (1, -1), (1, 0), (1, 1)}
Step-by-step explanation:
Since the Cartesian product A × A has 9 elements and contains (-1, 0) and (0, 1), the set A must have 3 elements.
The set A = {-1, 0, 1}
The remaining elements of A × A are the 7 other possible combinations of the 3 elements in A.
