IFactor Command
- IFactor( <Polynomial> )
-
Factors over the irrationals.
IFactor(x^2 + x - 1) gives \( \left( x + \frac{-\sqrt{5} + 1}\{2} \right) \left( x + \frac{\sqrt{5} +
1}\{2} \right)\)
CAS Syntax
- IFactor( <Expression> )
-
Factors over the irrationals.
IFactor(x^2 + x - 1) returns \( \left( x + \frac{-\sqrt{5} + 1}\{2} \right) \left( x + \frac{\sqrt{5} +
1}\{2} \right)\)
- IFactor( <Expression>, <Variable> )
-
Factors over the irrationals with respect to a given variable.
IFactor(a^2 + a - 1, a) returns \( \left( a + \frac{-\sqrt{5} + 1}\{2} \right) \left( a + \frac{\sqrt{5} +
1}\{2} \right)\)
