Factoring
Factor using the trial and error method for trinomials whose leading coefficient is not 1.
Step 1 — Find factor pairs of the first term. The only way to factor into a product of two first-degree terms is . Place these as the first terms of the binomials: .
Step 2 — Find factor pairs of the last term. Since all terms of the trinomial are positive, only positive factors of 2 are needed. The only factor pair is 1 and 2.
Step 3 — Test arrangements. The two factors 1 and 2 can be placed in either order, creating two trial factorizations:
- : inner product , outer product , sum ✓
- : inner product , outer product , sum ✗
The first arrangement produces a middle term of , which matches.
Step 4 — Check by multiplying: ✓
The factored form is . This example illustrates that even when the first term and the last term each have only one factor pair, the placement of the last-term factors still matters — swapping 1 and 2 between the two binomials changes the inner and outer products and produces a different middle term.
