Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Factoring Polynomials
Factoring polynomials involves rewriting a polynomial as a product of its factors. This process often includes identifying common factors, applying special product formulas (like the difference of squares or perfect square trinomials), and using techniques such as grouping. Understanding how to factor is essential for simplifying expressions and solving equations.

Factoring
Common Factors
A common factor is a number or variable that divides two or more terms without leaving a remainder. In the polynomial given, identifying the greatest common factor (GCF) among the terms is crucial for simplifying the expression. This step often leads to a more manageable form of the polynomial, making further factoring easier.

Factoring
Quadratic Trinomials
Quadratic trinomials are polynomials of the form ax² + bx + c, where a, b, and c are constants. They can often be factored into the product of two binomials. Recognizing the structure of a quadratic trinomial is important for applying the appropriate factoring techniques, such as finding two numbers that multiply to ac and add to b.
