x^3 - 5x - 2x^3 How do I solve this problem?

Directrix (directrix):

What are the instructions?

OpenStudy (anonymous):

Collect like terms.

OpenStudy (anonymous):

Wait... I see now what to do. I really should pay more attention to the instructions.

Directrix (directrix):

x^3 - 5x - 2x^3 The x-cubed terms are like terms. The x-to the first term is not a like term with the x-cubeds. What do you think the answer is?

OpenStudy (anonymous):

-x^3 - 5x

Directrix (directrix):

That is correct.
