Question 456212: Essay; show all work. Bob’s Barber Shop estimates their gross revenue for the second quarter to be given by the polynomial 2x3 – 3x2 + 7x – 1. The shop estimates their costs for that quarter to be given by x2 + 4x + 2. For the second quarter, find and simplify a polynomial that will represent their profit.

"profit" = "revenue" - "cost"
"profit" = (2x^3 – 3x^2 + 7x – 1) - (x^2 + 4x + 2)
"profit" = (2x^3 – 3x^2 + 7x – 1) - x^2 - 4x - 2
"profit" = 2x^3 – 3x^2 + 7x – 1 - x^2 - 4x - 2
"profit" = 2x^3 – 4x^2 + 7x – 1 - 4x - 2
"profit" = 2x^3 – 4x^2 + 3x – 1 - 2
"profit" = 2x^3 – 4x^2 + 3x – 3
