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 = ?
