Answer 1

Hi bittneyy18rm :)

How are you dear?

Answer 2

So your equation looks like this?
\[\Large 400x^8-36\]
Right?

Answer 3

I'm good haha thanks for asking :) and yes, it does look like that haha..

Answer 4

\[\large 400x^8 -36\]
\[\large (20x^4)^2-(6)^2\]
Now it is the formula, \(a^2-b^2=(a+b)(a-b)\)
\[\large (20x^4-6)(20x^4+6)\]
Now you have factored.
