1. Wait patiently for a helper to come along.
2. Once someone helps you, say thank you and close the thread with:

+close

3. Feel free to nominate the person for helper of the week in #helper-nominations
4. Do not ping the mods, unless someone is breaking the rules.
5. If you're happy with the help you got here, and the server overall, you can contribute financially as well:

According to the integer root theorem, you need to try factors of 10 (both positive and negative). So:
x = ±1
x = ±2
x = ±5
x = ±10
No need to check all of them: if you find one, say, x = x0, divide the polynomial by (x - x0). Then you'll get a quadratic polynomial, which is easy to find roots for.

I think it should be factors of 7? Is that not 17 - 10 at the end?
