Polynomials are really important when it comes to making the most money in business. They help companies understand how different things, like costs and sales, are related to one another. By creating a polynomial equation for profit, businesses can figure out the best way to maximize their earnings.

Example:

Let's look at a company where the profit ( P(x) ), based on the number of items ( x ) sold, is shown by this polynomial:

$P(x) = -2x^2 + 40x - 100$

Here, the term ( -2x^2 ) means that after a certain point, selling more items might not help the company make more money.

Steps for Optimization:

1. Find the Peak: Use the formula ( x = -\frac{b}{2a} ) to discover how many items should be sold to earn the highest profit.
2. Check the Profit: Plug that number ( x ) back into the profit equation to find out the maximum profit.

By using this method, businesses can make smart choices about how much to produce.
