Polynomial Factor
A Factor of a Polynomial 
of degree 
is a Polynomial 
of degree less than which can bemultiplied by another Polynomial 
of degree less than to yield , i.e., a Polynomial suchthat
For example, since
both
and 
are Factors of 
. The Coefficients of factorPolynomials are often required to be Real Numbers or Integersbut could, in general, be Complex Numbers.See also Factor, Factorization, Prime Factorization- Archimedes' Lemma
