The following problems are wrong

3: What's 6-10?

12: Check your signs carefully.

16: You added and you should have subtracted.

17: Check your signs again.

18: Completely wrong.

20: You only have one q^2 term, which is -6q^2, and only one choice starts with that..

**If you have something like 6-7x, when written the opposite way it becomes -7x+6. You got several wrong because of this.
