When do we only consider pairs of positive factors?

We see that the only pair of factors whose product is 12 and whose sum is 7 is 3 and 4. Thus, Note that when all terms of a trinomial are positive, we need only consider pairs of positive factors because we are looking for a pair of factors whose product and sum are positive. That is, the factored term of

#### When to consider pairs of positive factors in trinomial?

Consider the following pairs of factors whose product is 12. We see that the only pair of factors whose product is 12 and whose sum is 7 is 3 and 4. Thus, Note that when all terms of a trinomial are positive, we need only consider pairs of positive factors because we are looking for a pair of factors whose product and sum are positive.

#### What are the rules for using positive and negative integers?

How to find the product of two binomial factors?

When we have a monomial factor and two binomial factors, it is easiest to first multiply the binomials. Write 3x (x – 2) (x + 3) without parentheses. In Section 4.3, we saw how to find the product of two binomials.
