Provide an appropriate response.When is the square of the sum the sum of a square; i.e., when is (A + B)2 = A2 + B2 ?

What will be an ideal response?


Now (A + B)2 = A2 + 2AB + B2, so that (A + B)2 = A2 + B2 just in case 2AB = 0, that is A = 0 or B = 0. The square of the sum is the sum of the squares in the case (at least) one of the numbers is 0.
