3) for any factorable trinomial x^2+bx+c, will the absolute value of b sometimes,always, or never be less than the absolute value of c? explain
idk
4) give an example of a trinomial that can be factored using the factoring techniques presented. then factor the trinomial. idk
5) factor (4y5)^2 + 3(4y5)70
i got this
Make the simplifying substitution
z = (4y5):
z^2 + 3z  70
Factor:
(z + 10) (z  7)
Undo the substitution:
((4y5) + 10) ((4y5)  7)
Combine like terms:
(4y + 5) (4y  12)

Please go back and see my last comment on your first questions. I got distracted and gave you some incorrect info. Sorry.

ok

can you help me this

3) sometimes
4) what techniques were presented?
5) correct 
3) why is it sometmes
4) idk 
(x  2)(x + 8) b is less than c
(x  5)(2x + 1) b is greater than c
