It's a very simple question, and it's not even for homework. Well, technically it is for homework, but it's not the homework question. I just forgot what this was.

Question:

What is the difference of squares formula?

Again, not a homework question, I literally just forgot what it was.

Thanks for helping!

Ah, let me find this in my notes

anonymous · Answer

K, thx :)

sleepyjess · Answer

$a^2 - b^2 = (a – b)(a + b)$

anonymous · Answer

Alright. So for (x^2 - 9), the difference of squares would be:

(x^2 - 3^2) = (x - 3)(x + 3), correct @sleepyjess ?

sleepyjess · Answer

And as proof, 
$4^2 - 2^2 = \(4-2)(4+2)\(2)(6)\12\4^2 - 2^2 =\16 - 4\12$

sleepyjess · Answer

Yep :)
