Rules for Factoring Trinomials
- GCF Rule: Start by factoring out the greatest common factor among the coefficients.
- Special Cases Rule: Recognize and apply specific patterns for perfect square trinomials and the difference of squares.
- Factoring by Grouping Rule: For trinomials with four terms, group them and factor out common terms from each group.
- Factoring with Leading Coefficient Rule: For trinomials in the form (ax2 + bx + c), use methods like trial and error, grouping, or the AC method.

Trinomials
A trinomial is a type of polynomial that consists of three terms. These terms are usually written as ax² + bx + c, where a, b, and c are constants, and x is the variable. Trinomials are common in algebra, particularly when dealing with quadratic equations, which can often be expressed or factored into trinomial form.
It is the expression that consist of three terms, the common form of trinomial is ax2 + bx + c. Trinomials in algebra, are essential for solving quadratic equations and analyzing various mathematical models.
