You're missing something and that's completely understandable. It's not a reasonable problem for the time constraint and the people meant to be solving it. So what you need to do is consider P(x)-x. As that is equal to greater than 0, it means that any roots it has need to be even. Pic related is clear enough I hope. I apologize if the picture is sideways, not sure why it does it sometimes.
