Factoring Trinomials of the Form Using the ac Method
The "ac" method (also called the grouping method) is a systematic alternative to trial and error for factoring trinomials of the form . It extends the approach used for trinomials with a leading coefficient of 1 — where two numbers whose product and sum match the constant and middle coefficient are sought — by incorporating the product and then applying factoring by grouping. Because the method follows a fixed sequence of steps, it is very structured and always works. The procedure has six steps:
- Factor any GCF from all three terms before proceeding.
- Find the product (the coefficient of the squared term multiplied by the constant term).
- Find two numbers and such that and .
- Split the middle term into two terms using and : rewrite as . This converts the three-term trinomial into a four-term polynomial.
- Factor by grouping. Group the four terms into two pairs and factor the GCF from each pair, then extract the common binomial factor.
- Check by multiplying the factors to verify they produce the original trinomial.
The key insight is that the numbers and whose product equals and whose sum equals provide exactly the right decomposition of the middle term so that factoring by grouping succeeds. When the constant term is negative, the product will typically be negative as well, so the two numbers and must have opposite signs — one positive and one negative.
