Training Guide: Factoring multi-zone material cost formulas

Imagine you are an assistant estimator at a construction company. You are mentoring a new intern who needs to simplify a multi-zone material cost formula represented by the polynomial expression: 8x3y10x2y2+12xy3{}8x^3y - 10x^2y^2 + 12xy^3

Write a short training guide that recalls and explains the step-by-step process of factoring this polynomial by extracting the Greatest Common Factor (GCF). In your guide, you must do the following:

  1. State the GCF of the three terms and explain how you determined both the numerical part and the variable powers for xx and yy.
  2. Show how to rewrite each of the three terms of the polynomial as a product of the GCF and its remaining factors.
  3. Provide the final fully factored form of the expression.
  4. Explain how the intern can verify their factored answer to ensure it is correct.
