- ComplexRoot[<Polynomial>]
- Finds the complex roots of a given polynomial in x. Points are created in Graphics View.

## CAS Syntax

- ComplexRoot[<Polynomial>]
- Finds the complex roots of a given polynomial in x.
**Example:**`ComplexRoot[x^2 + 1]`

gives*{x = ί, x = -ί}*, the complex roots of*x*.^{2}+ 1

**Note:**

- The complex ί is obtained by pressing ALT + i.
- See also CSolve Command.
