Question

a^2-b^2
= (a) ^2 - (b) ^2
=(a-b) (a+b)​

Answer 1

Answer:

(a^2 )- (b^2)=(a-b)(a+b)

Step-by-step explanation:

when,(a-b)^2. = a^2 - 2ab + b^2

But here is (a)^2 - (b)^2= (a+b) × (a-b)

and when we multiply these

we get a^2 - ab + ba - b^2 then ,-ab, +ab get cancelled we get a^2 - b^2.

Answer 2

If we multiply (a+b)(a-b)

then we get

=a^2+ab-ab-b^2

=a^2-b^2
