# %z

A variable used to define polynomials.

`%z`

### Description

`%z` is the polynomial in the complex cases by default, `z = poly(0, "z")`. This variable is used to create polynomials.

### Example

```p = %z^2 + 2 * %i *%z -1
roots(p)
coeff(p)

z = poly(0, "z");
p1 = z^2 + 2*%i*z -1
roots(p1)
coeff(p1)```
