As part of a Quality Assurance (QA) initiative in the finance department, you are required to write a brief procedural summary for a new trainee. From memory, explain the step-by-step process of multiplying the binomial factors (3y1)(3y - 1) and (2y6)(2y - 6) using the Vertical Method. In your response, clearly identify the two partial products generated and describe how they are aligned in columns to arrive at the final result: $6y^2 - 20y + 6$.
