I have a few problems I am stuck on. They include dividing fractions that include factoring first.

1.) (w-4)^2 over 4-w^2 divided by w^2 - 16 over w-2

2.) 2c-4 over 8 divided by 2-c over 2.

3.) x^3 - 1 over x^4 -1 divided by 3x^2 + 3x +3 divided by x^3 + x^2 + x + 1.

Thanks, I used the term "over" which means it's being divided by that on it's own side.
