Understanding Factoring Trinomials
What Are Trinomials?
A trinomial is a polynomial with exactly three terms, typically expressed in the form:
- ax2 + bx + c
where:
- a is the coefficient of the quadratic term (x2)
- b is the coefficient of the linear term (x)
- c is the constant term
The Goal of Factoring
Factoring a trinomial involves expressing it as a product of two binomials:
- (px + q)(rx + s)
such that when multiplied out, you retrieve the original quadratic expression.
Why Is Factoring Important?
Understanding how to factor trinomials is crucial because:
- It simplifies solving quadratic equations by setting each binomial equal to zero (zero product property).
- It aids in graphing quadratic functions by identifying roots and intercepts.
- It's foundational for higher-level mathematics, including polynomial division and algebraic manipulation.

Types of Trinomials and Factoring Strategies
Factoring Trinomials with Leading Coefficient 1 (Simple Trinomials)
When a = 1, the trinomial takes the form:
- x2 + bx + c
Strategies include:
- Finding two numbers that multiply to c and add to b.
- Expressing the trinomial as (x + m)(x + n), where m and n satisfy the above conditions.
Example:
Factoring x2 + 5x + 6 involves:
- Finding two numbers that multiply to 6 and add to 5: 2 and 3.
- Factored form: (x + 2)(x + 3).
Factoring Trinomials with Leading Coefficient Not Equal to 1
When a ≠ 1, the process becomes more complex. The general form is:
- ax2 + bx + c
Common strategies include:
- Trial and Error / Guess and Check: Testing possible factors systematically.
- AC Method: Multiply a and c, find two numbers that multiply to ac and add to b, then split the middle term.
- Grouping: Rewriting the middle term using the two numbers found, then factoring by grouping.
Example:
Factor 6x2 + 11x + 3:
- Multiply a and c: 6 3 = 18.
- Find two numbers that multiply to 18 and add to 11: 9 and 2.
- Rewrite as: 6x2 + 9x + 2x + 3.
- Group: (6x2 + 9x) + (2x + 3).
- Factor each group: 3x(2x + 3) + 1(2x + 3).
- Final factored form: (3x + 1)(2x + 3).
