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.

Online "^" is used to indicate an exponent, e.g., x^2 = x squared.
2x^3 – 3x^2 + 7x – 1  (x^2 + 4x + 2) =
2x^3 – 3x^2 + 7x – 1  x^2  4x  2 = ?
