All right. Where are you confused here?

Can you create one on your own, Lou?

Yeah
Difference of squares- (r+2)(r-2)
Perfect squares- (r+7)^2

That's right. You already completed part II!

How about Part III?

remembered* and would that just be it?

That's totally correct :)
Yes.

lol oh okay :)

Wait hey what would be part I? would I just multiply what I did for part II to get it?

K parth :)

Like you said: (r + 2)(r - 2) and (r + 2)^2

Though, multiply it out to simplify it.

K that's what I thought :) thx a ton! :)

You're welcome!
