When a production manager sets a polynomial expression representing manufacturing costs equal to a target budget (for example, ${}0.05x^2 + 3x = 450$), this mathematical statement containing an equals sign is classified as a polynomial ________.

A manufacturing company uses mathematical formulas to model production costs and estimate shipping times. As a training coordinator, you are designing a workflow to help new hires verify whether a specific engineering formula is classified as a 'polynomial equation'. Arrange the following steps in the correct logical sequence to perform this classification, from the initial check to the final determination.
