Answer: plus or minus 1, 1/2, 2, 5, 5/2, and 10
Explanation:
To find the possible roots
We first find the factor of the constant term:
10: 1, 2, 5, 10
Then we find the factor of leading coefficient:
2: 1, 2
And the possible rational roots are:
Plus or minus [1/1, 1/2, 2/1, 2/2, 5/1, 5/2, 10/1, 10/2]
Then we get rid of the duplicate:
Plus or minus [1, 1/2, 2, 5, 5/2, 10]
Answer is A, pattern repeats.

<em>Comment on this solution</em>
When a problem statement tells you the ratio of one kind of item to another, it is often convenient to group the items in that ratio and deal with the groups. Sometimes, there will be a few missing or left over, for example "10 more than 3 times as many." In those cases, you can make an adjustment to the total and still deal with the groups. (Any equations you might write will effectively do this same thing.)
