General simplification
[src]
$$z^{3} - 3 z^{2} + z + 5$$
(x + 1)*(x + -2 + I)*(x + -2 - I)
$$\left(x + 1\right) \left(x + \left(-2 + i\right)\right) \left(x + \left(-2 - i\right)\right)$$
((x + 1)*(x - 2 + i))*(x - 2 - i)
Rational denominator

$$z^{3} - 3 z^{2} + z + 5$$
/ 2 \
(1 + z)*\5 + z - 4*z/
$$\left(z + 1\right) \left(z^{2} - 4 z + 5\right)$$
$$z^{3} - 3 z^{2} + z + 5$$
Combining rational expressions
