Factoring Using the ac Method
Factor the trinomial using the ac method.
Step 1 — Factor any GCF. The terms , , and share no common factor.
Step 2 — Find the product . Here and , so .
Step 3 — Find two numbers and that multiply to 12 and add to 8. 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 .
