20 L3 §1.4 Factoring Factoring – the process of finding polynomials whose product is equal to a given polynomial. A polynomial is considered to be factored completely if it is written as a product of prime or irreducible polynomials. Factoring out the GCF ( Greatest Common Factor ): Use the distributive property to factor out the GCF. The GCF is the product of the largest common factor of all numbers and all common factors containing variables, each with the smallest exponent that appears on that factor. Example . Factor out the GCF from each polynomial: a) 5 3 9 8 6 x y xy + b) 2 3 2 5 ( 2) ( 2) x x x x +
