Key Concepts
New Concept Finding the GCF means finding the largest monomial that divides without a remainder into each term of a polynomial. What’s next Next, you'll apply this concept to factor polynomials and simplify algebraic fractions, transforming them into their most basic forms.
Common Questions
How do you simplify an expression using the GCF?
Find the greatest common factor of all terms, then factor it out using the distributive property. Divide each term by the GCF and write the result as GCF × (remaining expression).
What is the greatest common factor (GCF)?
The GCF is the largest number or expression that divides evenly into all terms of an expression. For example, the GCF of 12x² and 8x is 4x.
Why is factoring out the GCF useful in algebra?
Factoring out the GCF simplifies expressions, makes further factoring easier, and helps solve equations by reducing terms to their simplest form.
