I need to know the step by step in doing the problem.
I'm so glad you replied. I made a sign error mistake.

The revenue is 2x³+5x²-x-1. The cost is 4x²-9x-8. To find the profit, you need to subtract the cost from the revenue.
(2x³ + 5x² - x - 1) - (4x² - 9x - 8) = (2x³ + 5x² - x - 1) + (-4x² + 9x + 8) = 2x³ + x² + 8x + 7

Do you need a longer explanation? If so, I can make a word file so I can format it better.

If you don't mind making a word file that would be great.
I'll get right on it.
