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

1. Check for gcf (which is 1). 2. Search for two integer factors of 15, whose sum is 8. 3. Finding 3 and 5, write$:\qquad (x+5)(x+3)$
1. The gcf is 1. Nothing to extract (factor out). 2. We want to write the factorization in the form $(x\pm...)(x\pm...)$, so we search for two integer factors of 15, whose sum is 8. ... we find 5 and 3, so we write = $(x+5)(x+3)$
