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)
