Answers
Before you understand A + B Whole Square : (a + b)2 = a2 + b2 + 2ab, you are advised to read:

What is Exponential Form ?
How this identity of (a + b)2 = a2 + b2 + 2ab is obtained:
Taking LHS of the identity:
(a + b)2
This can also be written as:
= (a + b) (a + b)
Multiply as we do multiplication of two binomials and we get:
= a(a + b) + b(a + b)
= a2 + ab + ab + b2
Add like terms and we get:
= a2 + 2ab + b2
Rearrange the terms and we get:
= a2 + b2 + 2ab
Hence, in this way we obtain the identity i.e. (a + b)2 = a2 + b2 + 2ab

Answer:
(a+b)^(2)
Step-by-step explanation:
(a+b)^(2)
(a+b)(a+b)
a(a+b)+b(a+b) (distributive property of multiplication over addition)
a^(2)+ab+ab+b^(2)
a^(2)+2ab+b^(2)
