(a+b)²=a²+2ab+b²

This is your answer

Answer 2

$\large {\purple {\tt {{(a + b)}^{2} = {a}^{2} + 2ab + {b}^{2}}}}$

It is known as the First Identity.

The other identities are as follows:

1. (a+b)^2 = a^2 + 2ab + b^2
2. (a-b)^2 = a^2 - 2ab + b^2
3. a^2 - b^2 = (a-b) (a+b)
4. (x+a)(x+b) = x^2 + (a+b)x + ab
