## Introductory Algebra for College Students (7th Edition)

1. Recognize a trinomial with a leading coefficent of 1 (seach for two integer factors of $+6$, whose sum is $-5$. ) 2. Since their product is positive and their sum is negative, both (if they exist) are negative.
First, check if there is a common factor other than 1. There are none. 1. Recognize a trinomial with a leading coefficent of 1 (seach for two integer factors of $+6$, whose sum is $-5$. ) 2. Since their product is positive and their sum is negative, both (if they exist) are negative. 3. Having found them to be $-3$ and $-2,$ write $(x-2)(x-3)$
