It seems that it's putting negatives in the next highest degree if you call it with a '/npc' command, for some reason.. It wasn't doing this when I first made it, weird.

You take the negative and positive of each factor of the lowest degree (reason abs is used in the script) and divide them by the negative and positive of each factor of the highest degree, then do synthetic division of the top numbers by each of the bottom numbers. If the end result is 0, you have a factor of the equation.
