Question

Essay; show all work. Bob’s Barber Shop estimates their gross revenue for the second quarter to be given by the polynomial 9x^3 + 4x^2 – 6x + 9. The shop estimates their costs for that quarter to be given by 7x^2 + 2x + 1. For the second quarter, find and simplify a polynomial that will represent their profit.

Answer 1

\[( 9*x^3 +4*x^2 - 6*x + 9 ) - ( 7*x^2+2*x+1 )\]

\[9*x^3-3*x^2-8*x+8\]
