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 (4y-5)^2 + 3(4y-5)-70

i got this

Make the simplifying substitution
z = (4y-5):
z^2 + 3z - 70
Factor:
(z + 10) (z - 7)
Undo the substitution:
((4y-5) + 10) ((4y-5) - 7)
Combine like terms:
(4y + 5) (4y - 12)
