Step-by-step explanation:

Let a and b be the two numbers, the squares of a and b are a2 and b2. The sum of the squares of a and b is a2 + b2. We could obtain a formula using the known algebraic identity (a+b)2 = a2 + b2 + 2ab. On subtracting 2ab from both the sides we can conclude that a2 + b2 = (a +b)2 - 2ab.
