## Algebra 1: Common Core (15th Edition)

We would try rewriting the middle term by first finding factors of $4\cdot 15$ whose sum is 23. Factors of $60$ with a sum of $23$, ... are $20$ and $3$. $...=4w^{2}+20w+3w+15$ By factoring each group, the same factor would appear in both pairs of terms, $w+5$. So, yes, we would factor this polynomial by grouping.
