CAS Syntax
- CIFactor[ <Expression> ]
- Factors over the complex irrationals.
- Example:
CIFactor[x^2 + x + 1]
returns \left( x + \frac{-ί \sqrt{3} + 1}{2} \right) \left( x + \frac{ί \sqrt{3} + 1}{2} \right)
- CIFactor[ <Expression>, <Variable> ]
- Factors over the complex irrationals with respect to a given variable.
- Example:
CIFactor[a^2 + a + 1, a]
returns \left( a + \frac{-ί \sqrt{3} + 1}{2} \right) \left( a + \frac{ί \sqrt{3} + 1}{2} \right)
