You can put this solution on YOUR website! When dividing the polynomials by synthetic division, what are the numbers we list across the top row in the division?
(2x^4-x^2+5x-7)/(x+4)
------------------
Answer: The coefficients of the polynomial.
Example:
-4....2.....0....-1,,,,5,,,..,-7
........2....-8....31...-119..|..469
---------
Quotient: 2x^3-8x^2+31x-119
Remainder: +469
Also f(-4)=-+469 by the Remainder Theorem
