I have some questions that I need help with , and here they are:

1) Find the GCF of a) 8x(2y+3); 4(3+2y)
b) 8x^4 z( 2y+3)^3 ; 4x^2 ( 3+2y)

2) Factor completely: a) 4q(x-3y) + 7p(3y-x)
b)5c(m+5n) -10(5n-m)
c) (2w+3)^2 + 4(2w+3) -12
d)9x^2 - 25y^4
------- --------
4 121

If you can help me, I would GREATLY APPRECIATE IT!! :D :D

These are very straight forward. 2a,b are done except for one more step.

2c is a little trickier. It will expand into a quadratic, 4w^{2}+20w+9

Factor it. (2w+?)(2w+?)

I will give you a freebie, 2d:

Difference of two squares. (3x)^{2}-(5y^{2})^{2}

(3x-5y^{2})(3x+5y^{2})

See?
