Para os exercícios a seguir, use a divisão longa para encontrar o quociente e o restante.

19. $$\frac{x^{3}-2 x^{2}+4 x+4}{x-2}$$

20. $$\frac{3 x^{4}-4 x^{2}+4 x+8}{x+1}$$

Para os exercícios a seguir, use a divisão sintética para encontrar o quociente. Se o divisor for um fator, escreva a forma fatorada.

21. $$\frac{x^{3}-2 x^{2}+5 x-1}{x+3}$$

22. $$\frac{x^{3}+4 x+10}{x-3}$$

23. $$\frac{2 x^{3}+6 x^{2}-11 x-12}{x+4}$$

24. $$\frac{3 x^{4}+3 x^{3}+2 x+2}{x+1}$$
