so how do i solve this? I did this: If does this help me in anyway? i can put those values instead of x-es.. a = 1 - b = 1. is that how you do it?

Edit* Made some silly errors...

The way I did it is: As previously stated, if is a factor, then Now if you divide by you get: Now for to be a second factor. Which gives and i think should be and or now, we have two equations in and , solve it

im lost.. from that i get b = 2007 a = -2006 im getting more and more confused.. what is wrong with my solution btw? :P
