*(Factor completely)*

1.$\displaystyle 9x^7-18x^4+36^6$

*So far I've gotten to...*

$\displaystyle 9x^7/9^4-18x^4/9^4+36^6/9^4$

$\displaystyle x^3-2+4^2$

And I'm at a pause there.

(Factor trinomial)

2.$\displaystyle C^2+10cg+16g^2$

*Not sure if this is right.*

$\displaystyle (c+2g)(c+8)$

*I have no clue whatsoever on how to solve this one.*

(Factor)

3.$\displaystyle 2x^4 - 4x^2$

Likewise.

(Factor by grouping)

4.$\displaystyle 7z^2 +14z -az -2a$
