Answer 1

Resposta:

$-8$

Explicação passo a passo:

$P(x)=2x^3-4x^2+x-1\ e\ G(x)=x+1\\\\\left\begin{array}{ccc}2x^3-4x^2+x-1\\-2x^3-2x^2+0+0\\---------\\0-6x^2+x-1\\0+6x^2+6x+0\\---------\\0+0+7x-1\\0+0-7x-7\\---------\\0+0+0-8\end{array}\right| \left\begin{array}{ccc}x+1\\------\\2x^2-6x+7\end{array}\right$

$R(x)=-8$
