Work Step by Step

All terms are divisible by $4y$, so factor out $4y$ to obtain: $=4y(y^2+3y-18)$ Factor the trinomial. Look for factors of $-18$ whose sum is $3$. These factors are $6$ and $-3$. This means that the trinomial can be factored as $(y+6)(y-3)$. Thus, the completely factored form of the given polynomial is: $=4y(y+6)(y-3)$
