alright, my math is easy but theres always a few hard ones. just wondering if anyone can do these, show restrictions and show as much work as possible, or explain the steps.

4 | 5

--------- | - -----------

y^2+5y+6 | y^2-y-12

4 | 3

--------- | + -------------

w^2+5w+4 | w^2+2w+8

6b^3 |+ 9g^5

------- | ---------

8g^5 | 12b^3

1 + | 4 |- 6

-------|------ | -------

2x^2 | 3x | x^3

Thanks for any help
