Answer:

-3q(4q^2+q+3)

Step-by-step explanation:

To solve this question we will have to open the bracket first

So let's solve

(-9q^3+(-8q)+(3q^2-q-6q^3)

Open the bracket first

(-9q^3-8q)+3q^2-q-6q^3

-9q^3-8q+3q^2-q-6q^3

Let's collect like terms

-9q^3-6q^3+3q^2-8q-q

-12q^3+3q^2-9q

We can actually factorise

-3q(4q^2+q+3)
