Factoring
Factor completely using the trial and error method.
Step 1 — Write in descending order. The trinomial is already in descending order.
Step 2 — Find factor pairs of the first term. The term can be factored as or .
Step 3 — Find factor pairs of the last term and consider signs. The last term is negative, so its factors must have opposite signs: and .
Step 4 — Test all combinations. Combining each pair of first-term factors with each pair of last-term factors produces eight trial factorizations. Since the original trinomial has no greatest common factor (GCF), any trial binomial containing a common factor (e.g., contains a common factor of 7) can be eliminated immediately. Testing the remaining four combinations for the correct middle term ():
