Question

9. Divide 3x^3 + 3x^2 + 2x – 2 by x + 3 using long division. (1 point)

3x^2 – 6x + 20
3x^2 + 12x – 16
3x^2 + 12x – 16, R 58
3x^2 – 6x + 20, R -62

10. Divide using synthetic division.

–3x^3 + 11x^2 – x + 20 by (x – 4). (1 point)

–3x^2 + 23x + 3, R 40
–3x^2 – x – 5
3x^2 + x + 5
3x^2 – 23x – 3, R –40

Answer 1

1;3x^2 + 12x – 16
2;3x^2 – 23x – 3, R –40

Answer 2

thank you so much!
