Question 499426: 9. Essay; show all work. Bob�s Barber Shop estimates their gross revenue for the second quarter to be given by the polynomial 6x^3 + 9x^2 � x � 2. The shop estimates their costs for that quarter to be given by 3x^2 + 4x � 8. For the second quarter, find and simplify a polynomial that will represent their profit. Note: Profit = Revenue - Costs
please help me with this problem I am not good at these word problems.

Just subtract the cost from the revenue, pretty straightforward.

Profit = (6x^3 + 9x^2 - x - 2) - (3x^2 + 4x - 8) = 6x^3 - 6x^2 + 5x + 6

Note that you have to distribute the minus sign throughout.
