Bob’s Barber Shop estimates their gross revenue for the second quarter to be given by the polynomial 5x3 – 9x2 – 2x – 3. The shop estimates their costs for that quarter to be given by x2 + 4x + 7. For the second quarter, find and simplify a polynomial that will represent their profit. Note: Profit = Revenue - Costs  </SPAN>\n" );
