In a software development project, a programmer is optimizing a quadratic formula y^2 - 6y + 15. After testing the factor pairs (-1, -15) and (-3, -5) and finding that neither sums to -6, the programmer labels the expression as which of the following?

A small business owner is using the quadratic expression y^2 - 6y + 15 to model monthly utility costs. After checking all possible integer factor pairs of 15 and finding that none of them add up to -6, the owner concludes the expression cannot be simplified through factoring. This type of non-factorable expression is called a ____ trinomial.

A student in a developmental math workshop is documenting the process used to prove that the expression $y^2 - 6y + 15$ is a prime trinomial. Arrange the following steps in the correct order to reflect the systematic verification strategy.

A junior analyst is documenting the systematic factoring of the expression $y^2 - 6y + 15$ for a performance report. Match each value or conclusion from the factoring strategy with its correct description.

A warehouse inventory manager is using the quadratic expression $y^2 - 6y + 15$ to model the fluctuations in stock levels. When applying the trinomial factoring strategy to this expression, why must the manager only test factor pairs where both numbers are negative?

An operations analyst is documenting why the expression $y^2 - 6y + 15$ is classified as a prime trinomial. After testing the factor pair (-3, -5) and finding a sum of -8, what is the primary reason this specific result supports the 'prime' classification?

True or False: $y^2 - 6y + 15$ is a prime trinomial.
