I took a break for 2 semesters away from math and it has turned out to be a big mistake. I can't even remember basic factoring.

I need an explanation on how to solve these problems or if you don't have the time, just solve them for me and i'll figure them out:

Factor completely -

4w + 12 - zw - 3z

9r + 24t

2p(p is cubed) + 8p(p is squared) - 10p

t(squared) - 100

b(cubed) - 27

Solve:

z(squared) + 11z + 24 = 0

25x(x is squared) + 4 = 20x

Thanks
