Factoring Trinomials of the Form
To factor a trinomial of the form — a two-variable version of the standard pattern — use the same factor-pair strategy with one additional structural observation about the second variable.
In the trinomial :
- The first term is the product of the first terms of the two binomial factors: . This tells us each binomial begins with .
- The last term contains , which means the second term of each binomial factor must include a factor of .
- The coefficients and are handled exactly as in the single-variable case: find two numbers and such that and .
The factored form is . The numbers and become the coefficients of in each binomial, rather than standalone constant terms as in the single-variable case.
For example, to factor , find two numbers whose product is 36 and whose sum is 12. The pair 6 and 6 works, so the factored form is .
