$$z^{3} + 11 z^{2} + 36 z + 26$$
/ 2 \
(1 + z)*\26 + z + 10*z/
$$\left(z + 1\right) \left(z^{2} + 10 z + 26\right)$$
(1 + z)*(26 + z^2 + 10*z)
Combining rational expressions

$$z \left(z \left(z + 11\right) + 36\right) + 26$$
26.0 + z^3 + 36.0*z + 11.0*z^2
26.0 + z^3 + 36.0*z + 11.0*z^2
$$z^{3} + 11 z^{2} + 36 z + 26$$
$$z^{3} + 11 z^{2} + 36 z + 26$$
