Answer 1

Continue, lou
we all waiting for you

Answer 2

May I type it then?

Answer 3

Yeah sure. :)

Answer 4

No I guess you should

Answer 5

Okay, seems like Lou left.
There are two different ways to do this question:
* Actually multiply
* Use the identity \((a + b)( a- b) = a^2 - b^2\)

Answer 6

Which one would you like?

Answer 7

I'd like the first one for the understanding.

\( \color{Black}{\Rightarrow (6x + 2)(6x - 2)}\)

\( \color{Black}{\Rightarrow 6x(6x - 2) + 2(6x - 2) }\)

\( \color{Black}{\Rightarrow 36x^2 - 12x + 12x - 4 }\)

\( \color{Black}{\Rightarrow 36x^2 - 4 }\)
