Answer:
[tex]z ^ { 4 } +2z ^ { 3 } +3z ^ { 2 } +4z+5 \div z+4 \\ \\ \frac{\left(z^{4}+2z^{3}+3z^{2}+4z+4\right)z}{z}+\frac{5}{z} \\ \\ \frac{\left(z^{4}+2z^{3}+3z^{2}+4z+4\right)z+5}{z} \\ \\ \frac{z^{5}+2z^{4}+3z^{3}+4z^{2}+4z+5}{z} [/tex]
9.
[tex]\frac{t^{5}+t^{4}+4t^{3}+6t^{2}+3t+2}{t} \\ \\ \frac{\left(t^{4}+t^{3}+4t^{2}+6t+3\right)t}{t}+\frac{2}{t} \\ \\ \frac{\left(t^{4}+t^{3}+4t^{2}+6t+3\right)t+2}{t} \\ \\ \frac{t^{5}+t^{4}+4t^{3}+6t^{2}+3t+2}{t}[/tex]
