It doesn't have a unique formula but it can be derived by two formuals-:
(a + b)^2 = a^2 + b^2 + 2ab
(a - b)^2 = a^2 + b^2 - 2ab
So, a^2 + b^2 formula can be
a^2 + b^2 = (a + b)^2 - 2ab
a^2 + b^2 = (a - b)^2 + 2ab
(a + b)^2 = a^2 + b^2 + 2ab
(a - b)^2 = a^2 + b^2 - 2ab
So, a^2 + b^2 formula can be
a^2 + b^2 = (a + b)^2 - 2ab
a^2 + b^2 = (a - b)^2 + 2ab
a2 + b2 = (a+b)whole square- 2ab
but it can be (a-b)whole square +2ab
