Question

(a+b)(a+b) = ?

PLEASE SEND THE ANSWER​

Answer 1

Answer:

a^2 + ab + ab + b^2

Therefore ,

a^2 + 2ab + b^2

or

(a + b ) ^2

Answer 2

Answer:

Hence the value will be $(a+b)(a+b)=a^{2} +2ab+b^{2}$

Step-by-step explanation:

In accordance with the information provided in the question,

We have find the value of the supplied expression in the above question.

Given the data in question $(a+b)(a+b)$

As we know that

As the given equation is in form of

So, for finding the value of the expression we will first multiply "a" with "c" and a with  "d" and then multiply "b" with "c" and b with "d", and then add the resultant value.

So, value of expression we will be

$ac+ad+bc+bd$

$(a+b)(a+b)$

=$(a\times a)+(a\times b)+(b\times a)+(b\times b)\\a^{2} +ab+ba+b^{2} \\a^{2} +ab+ab+b^{2} \\a^{2} +2ab+b^{2}$
