# If A × B = {(a, x),(a , y), (b, x), (b, y)}. Find A and B

**Solution:**

It is given that A x B = {(a, x), (a, y), (b, x), (b, y)}

We know that the Cartesian product of two non-empty sets P and Q is defined as

P x Q = {(p, q) : p ∈ P, q ∈ Q}

Therefore, A is the set of all first elements and B is the set of all second elements.

Thus, A = {a, b} and B = {x, y}
