Best ResponseYou've already chosen the best response.1then lets simplify it, by multiply both sides by xa \[p(x)=(xa)~q(x)+r(x)\] do we still agree?

Best ResponseYou've already chosen the best response.1now, let x=a \[p(a)=\underbrace{(aa)}_{\color{red}{=0}}~q(a)+r(a)\] \[p(a)=r(a)\]

Best ResponseYou've already chosen the best response.1(x^3+2x^26x9) / (x+2) = q(x) + r(x)/(x+2) x^3+2x^26x9 = (x+2) q(x) + r(x) when does x+2 = 0?
