Answer 2

You have to find the largest number that divides into each term. I won't do all of them. You need to try some yourself.

1. 18(q - 3) If you can't get it right away, start with smaller numbers. For example:

9(2q - 6) You'll notice that 2 and 6 still have a common factor of 2. So take that out next
9*2(q - 3) = 18(q - 3) Same result.

Answer 3

1. 6(3q-9)
2. 7(6a-11)
3. 5(6+9s)
4. 10(5n+3)
5. 6(3+2d)
6. 3(9m+35)
7.13(5-3b)
8. 21(d-3)
9. 12(4+7m)
