## nicc96 2 years ago The area of a small square sample of carpet is 2w² - 7w – 15 in square yards. Which of the following could be the length of the sample? A. w – 3 B. 2w + 3 C. 2w - 5 D. w + 5 The area of a rectangular counter top is w2 – 3w – 10. Which of the following could be the length of the counter top? A. w – 10 B. w – 3 C. w + 2 D. w + 5

1. Numb3r1

This is asking you to factorize the trinomials.

2. Kaederfds

2w² - 7w – 15 = (2w+3) (w-5) [B]

3. Numb3r1

Correct, and the second one... (let them solve it, please)

4. Kaederfds

yes, @nicc96 now solve the other one (:

learn to factor!

7. dan815

8. nicc96

why are you screaming?

9. dan815

SO U LEARN TO FACTOR

10. nicc96

its not helping me.

11. dan815

bahahahahahah

12. dan815

do u want me to whisper!

13. nicc96

im about to close the question anyhow but thanks ways ...I think lol

14. dan815

u know how to factor that alreadY?

15. nicc96

not really.ill figure it out

16. dan815

ok, look up on youtube lots of videos!

17. nicc96

okayy

18. dan815

19. nicc96

3

20. nicc96

I think

21. dan815

fist think about the multiplying to -10 the adding part will come automatically

22. dan815

|dw:1368682177957:dw|

23. dan815

which one of those numbers that multiply to give - 10 add to give -3?

24. dan815

|dw:1368682262652:dw|

25. nicc96

yeah I think ill review this again but thanks for the help

26. dan815

ok

27. dan815

thats your best option! if you ask me! learn this still really well, its very important for later

28. dan815

learn factoring and quadratic equation, the 2 most important things at this level of math

29. Chris911

@dan815 wouldn't this be w+5 after u factor??

30. Chris911

@dan815

31. dan815

what w+5??

32. dan815

oh um the factor is (w-5)(w+2)= w^2-3w-10
