Okay, I hope this isn't one too many problems. So here's the problem with each of them.

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