4. The accounting department at Factory Shoe has determined that the quadratic relation P = - 2x²+ 24x - 54 models the company's profit. In this equation, P represents the profit (in $100 000s) and x represents the number of pairs of shoes sold (in 100 000s). a) Write the equation in factored form. (Note: you will need to use your factoring skills from the first unit). b) What are the zeros of the relation? What do they represent? c) Calculate the number of pairs of shoes that the company must sell to maximize its profit. How much would that maximum be?
