The following problems are wrong
3: What's 610?
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 67x, when written the opposite way it becomes 7x+6. You got several wrong because of this.
