## Loujoelou 3 years ago Part 1: Create a difference of squares binomial or a perfect square trinomial that can be factored multiple times. (1 point) Part 2: Provide the factors of this polynomial. (2 points) Part 3: Explain, in complete sentences, the process you used to create the binomial/trinomial. (2 points) I know how to make a difference of squares binomial and perfect squares one, but some parts of the question are unclear to me so yeah.

1. ParthKohli

All right. Where are you confused here?

2. ParthKohli

Can you create one on your own, Lou?

3. Loujoelou

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

4. ParthKohli

That's right. You already completed part II!

5. ParthKohli

6. Loujoelou

Um, I used my brain and rememberd difference of squares is always (a+b)(a-b) and perfect squares is always (a+b)^2 or (a-b)^2 and came up with one.

7. Loujoelou

remembered* and would that just be it?

8. ParthKohli

That's totally correct :) Yes.

9. Loujoelou

lol oh okay :)

10. ParthKohli

Just write something like: I made an expression in the form \(a^2 - b^2\), or \((a + b)^2\)(in the case of a perfect square).

11. Loujoelou

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

12. Loujoelou

K parth :)

13. ParthKohli

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

14. ParthKohli

Though, multiply it out to simplify it.

15. Loujoelou

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

16. ParthKohli

You're welcome!
