Documenting Quadratic Cost Optimization Solutions

A business analyst at a shipping company is writing a training guide for new team members. The guide includes a step-by-step demonstration of how to solve the operating cost equation 3x2=12x+63{}3x^2 = 12x + 63 using the factorization method.

Write an essay that reproduces this demonstration. In your response, make sure to:

  1. Explain how to rewrite the equation in standard form set to 0.
  2. Identify the numerical greatest common factor (GCF) and show how factoring it out simplifies the equation.
  3. Show the completely factored form of the trinomial.
  4. Explain how to apply the Zero Product Property to the factored equation, specifically explaining why the constant factor of 3{}3 does not yield a solution.
  5. Provide the two final solutions for xx.
