Terminology in Construction Costing

A junior estimator at a construction firm is using the Vertical Method to multiply a material cost expression (2b2βˆ’5b+8)(2b^2 - 5b + 8) by a quantity expression (b+3)(b + 3). In their calculation, the estimator generates two intermediate rows of resultsβ€”$6b^2 - 15b + 24 and $2b^3 - 5b^2 + 8bβ€”before summing them for the final total. What is the specific mathematical term used to describe these intermediate result rows?
