Question

(a+b) ka holl square

Answer 1

(a+b)²
(a+b)(a+b)
= a(a+b) + b(a+b)
= a² + ab + ab + b²
= a² + b² + 2ab

Answer 2

Answer:

$(a+b)$ whole square is equal to $a^{2}+2ab+b^{2}$.

Step-by-step explanation:

A square is the result of multiplying a number by itself.

We should find $(a+b)^{2}$.

We multiply $(a+b)$ to $(a+b)$ to find its square.

$(a+b)^{2}=(a+b)*(a+b)$

$=a^{2}+ab+ab+b^{2}$

$=a^{2}+2ab+b^{2}$

This expression $(a+b)^{2}$ is also called as FOIL method.

FOIL stands for First, Outer, Inner, Last.

Which means that first we multiply the first terms in the parenthesis, then we multiply the outer terms followed by inner terms multiplication and finally the multiplication of last terms in the parenthesis.

Multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life.

In arithmetic, the multiplication of two numbers represents the repeated addition of one number with respect to another.
