16. Fgcbear16

|dw:1347899213143:dw|

17. Fgcbear16

what goes there?

18. Fgcbear16

|dw:1347899423374:dw|

19. kiamonstaa

um...(x+3)(x-6)

20. Fgcbear16

if the middle term is positive, then the larger number is positive; if the middle term is negative, then the larger number is negative.

21. Fgcbear16

which is greater 3 or 6

22. kiamonstaa

6...so it would go at the bottom?

23. Fgcbear16

|dw:1347899769316:dw| 6 is larger and the middle term is positive. so 6 is positive and 3 is negative
