The remainder is =3x+2 and the quotient is =x-2

Explanation:

Perform the long division

color(white)(aaaa)x^3+0x^2+0x+0color(white)(aaaa)|x^2+2x+1

color(white)(aaaa)x^3+2x^2+xcolor(white)(aaaaaaaa)|x-2

color(white)(aaaaa)0-2x^2-x

color(white)(aaaaaaa)-2x^2-4x-2

color(white)(aaaaaaa)-0x^2+3x+2

The remainder is =3x+2 and the quotient is =x-2

(x^3)/(x^2+2x+1)=x-2+(3x+2)/(x^2+2x+1)
