If yes why? ie dividing by (x - 1) plud in a 1 and (x + 1) plug in -1 If you divide a polynomial by , you will get a quotient of one less degree plus a remainder with a constant numerator. So Now if you let , you have , so So yes, when you want to find the remainder when dividing a polynomial by , you plug in .
Thank you.
