Problema Solution
Bob 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. Profit- Revenue-Costs
Answer provided by our tutors
gross revenue second quarter: 9x^3+4x^2-6x+9
cost second quarter: 7x^2+2x+1
Find: profit?
Profit = revenue - cost
profit = 9x^3+4x^2-6x+9 - 7x^2-2x-1= 9x^3 -3x^2-8x+8
Profit = (9x^3) -(3x^2)-8x+8
