Factoring Using the ac Method
Factor by applying all six steps of the "ac" method to demonstrate how it converts a trinomial factoring problem into a factoring-by-grouping problem.
Step 1 — Factor any GCF. The terms , , and share no common factor, so proceed to the next step.
Step 2 — Find the product . Here and , so .
Step 3 — Find two numbers and that multiply to 12 and add to 7. Since both the product and sum are positive, both numbers must be positive. The pair and works: and .
Step 4 — Split the middle term into :
Step 5 — Factor by grouping. Group into two pairs and factor the GCF from each:
Both groups share the common binomial . Factor it out:
Step 6 — Check by multiplying: ✓
The factored form is . This example shows how the numbers 3 and 4 — whose product matches and whose sum matches — provide exactly the right way to split the middle term so that factoring by grouping produces two binomial factors.
