Algebra Homework Help : Factoring the GCF in Algebraic Expressions
How to factor the GCF in an Algebraic Expression ?
Factoring the Greatest Common Factor (GCF) out of an algebraic expression involves three steps:
Example 1. 8x^{4} + 4x^{2}−12x = 4x(2x^{3 }+ x − 3)
Example 2. ab^{3} − 2a^{2}b^{2} = ab^{2}(b − 2a)
Note that it is important to check the answer by expansion. Practice Exercise for Algebra Module on Factoring GCF in Algebraic Expressions
