Bob’s Barber Shop estimates their gross revenue for the second quarter to be given by the polynomial 8x3 – x2 – 2x + 4. 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.

P=(8X^3 -X^2 - 2X + 4) -(X^2 - 4X + T),
P = 8X^2 - 2X^2 + 2X - 3.
CORRECTION:
P=(8X^3 -X^2 -2X + 4) -(X^2 - 4X + 7),
P = 8X^3 - 2X^2 + 2X - 3.
