$$(a + b)^2$$

How to solve the sum of two whole square numbers

Suppose, if we get a question like $$(21+34)^2$$ Then there is a particular formula to solve it.

THE FORMULA IS: $$(a + b)^2 = a^2 + b^2 + 2ab$$

Let us work it out with an example:-

let a=25 and b=31

$$(a+b)^2 = a^2 + b^2 + 2ab$$

$$(25+31)^2 = 25^2 + 31^2 + (2*25*31)$$
