s^4 – 16

2. inkyvoyd

That's not a question.

3. dajapeay

factor this!!!! @inkyvoyd

4. inkyvoyd

(a+b)(a-b)=a^2-b^2

5. ajprincess

(s-4)(s+4)

6. inkyvoyd

aj, wrong.

7. inkyvoyd

s^4-16=(s^2+4)(s^2-4)=(s^2+4)(s-4)(s+4)

8. ajprincess

Sorry (s-2)(s+2)(s^2+4)

9. dajapeay

(s - 2)2(s + 2)2

10. dajapeay

that right

11. inkyvoyd

Daja, no.

12. dajapeay

heres my options.....

13. dajapeay

A. (s - 2)^2(s + 2)^2 B. (s - 2)(s + 2) C. (s - i)(s + i)(s - 2)(s + 2) D. (s - 2i)(s + 2i)(s - 2)(s + 2)

14. inkyvoyd

(s - 2)2(s + 2)2=(s - 2)(s - 2)(s + 2)(s + 2) =/=(s^2+4)(s-2)(s+2)

15. inkyvoyd

sorry, my first post was also wrong, those s's need 2's, not 4s. SHould be (s^2+4)(s-2)(s+2)

16. dajapeay

what is it either a b c d

17. inkyvoyd

D.

18. inkyvoyd

Factor (s^2+4)=(s-2i)(s+2i)

19. dajapeay

7m6n5 what is the degree is it 11

20. inkyvoyd

I'm not sure, I think so.

21. dajapeay

A machinist creates a washer by drilling a hole through the center of a circular piece of metal. If the piece of metal has a radius of x + 10 and the hole has a radius of x + 6, what is the area of the washer?

22. dajapeay

u no

23. inkyvoyd

pi((x+10)^2-(x+6)^2)

24. dajapeay

25. inkyvoyd

well, simplify the expression, and it IS the answer.

26. dajapeay

can someone give me the answer!
