Question

por favor me ajude resposta completa

Answer 1

P(x)=Q(x)*D(x)+R(x)

A)
$P(x)=(x^2-x+2)(x-2)+0 \\ P(x)=x^3-2x^2-x^2+2x+2x-4 \\ P(x)=x^3-3x^2+4x-4$

B)
$P(x)=(x-5)(2x+1)-3 \\ P(x)=2x^2+x-10x-5-3 \\ P(x)=2x^2-9x-8$


C)
$P(x)=(x+2)*(x^2-x-1)+(4x+1) \\ P(x)=x^3-x^2-x+2x^2-2x-2+4x+1 \\ P(x)=x^3+x^2+x-1$
