Question

(a+b) ×(a-b)प्ले पॉज ​

Answer 1

Answer:

The required value of $(a+b)\times(a-b)=a^{2} -b^{2}$

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 the given equation is in form of $(a+b)(a-b)$

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

$ac-ad+bc-bd$

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

Negative ab and positive ab are cancel we get,

$a^{2} -b^{2}$

Hence  the required value of $(a+b)\times(a-b)=a^{2} -b^{2}$

Answer 2

$(a + b) \times (a - b)$

$= a(a - b) + b(a - b)$

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

$= {a}^{2} - {b}^{2}$
