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
