Question

anonymous · Answer

Arrange it in the order of power, then subtract the like terms together!

anonymous · Answer

Can you start it off for me? @Chlorophyll Not sure how to.

anonymous · Answer

$$5x ^{3}-16x ^{2}-6x+7$$ Correct me I am wrong

anonymous · Answer

There is no option that begins with 5x. They all start with 4x. @dsanders520

anonymous · Answer

Ozzy I don't understand what you mean by starting with 4x

anonymous · Answer

It's 9x^3

anonymous · Answer

You wrote it wrong

anonymous · Answer

I can tell since 9x^3 - 5x^3 will give you 4^3

anonymous · Answer

Oh shoot thank you @Azteck for catching that mistake.

anonymous · Answer

-5x³ + 2x²    - 9x +3
        - 18x² ...

anonymous · Answer

Where did the 9x^3 come from

anonymous · Answer

The very start. It says (9x- 18x^2 - 6x +4). THe 9x is meant to be 9x^3
