Answer:
See proof below
Step-by-step explanation:
One way to solve this problem is to "add a zero" to complete the required squares in the expression of xy.
Let and with . Multiplying the two equations with the distributive law and reordering the result with the commutative law, we get
Now, note that by the commutativity of rational integers. Add this convenient zero the the previous equation to obtain , thus xy is the sum of the squares of .
