Bob's Barber Shop estimates thier gross reveue for the second quarter to be given by polynomial 5x^3-9x^2-2x-3 The Shop estimates the cost for that quarter to be given by x^2+4x+7 For the second quarter, find and simplify a polynomial that will represent their profit.

Solution:

The profit = Gross revenue - Cost = 5x^3-9x^2-2x-3 -(x^2+4x+7) = 5x^3-10x^2 -6x -10

So the profit = 5x^3-10x^2 -6x -10
