Question

(-9q^3+-8q) + (3q^2-q-6q^3) I need to find the sum

Answer 1

Answer:

−15q3+3q2−9q

Step-by-step explanation:

−9q3−8q+3q2−q−6q3

=−9q3+−8q+3q2+−q+−6q3

Combine Like Terms:

=−9q3+−8q+3q2+−q+−6q3

=(−9q3+−6q3)+(3q2)+(−8q+−q)

=−15q3+3q2+−9q

Answer 2

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)
