Answer 2

To find: The whole square of a plus b.

Step-by-step explanation:

• To find the square of a binomial, use the $(a+b)^{2}$ formula. This formula can also be used to factorize certain trinomials. One of the algebraic identities is this formula.
• The square of the sum of two terms is calculated using the $(a+b)^{2}$ formula.
• To factorize a binomial, the $(a+b)^{2}$ formula is commonly employed.

Solution:

Multiplying two terms: $(a+b)\times (a+b)=(a+b)^{2}$

∴ $a^{2}+ab+ba+b^{2}$

∴ $a^{2}+2ab+b^{2}$

Therefore, $(a+b)^{2}$ is $a^{2}+2ab+b^{2}$
