Answer 1

Answer:

It difficult to type but i will explain

You have to multiply first the powers like (a+b) with (a-b)and (b+c) with (b-c) and so on

After that as the base is same(x) so you have to add up the powers of the 3 x's and all of them would get cut giving a zero

So, x raised to power zero would be 1

and hence proved

I hope that helped:-)
