You are a logistics coordinator using a software tool that models warehouse space optimization using the polynomial $y^4 - y^2 - 20$. To debug an error in the code, you need to factor this expression using substitution. After recalling the substitution step and setting $u = y^2$ to create the standard quadratic trinomial $u^2 - u - 20$, what is the correct factored form of the expression in terms of the temporary variable $u$?

As a data analyst for a global shipping company, you are documenting the factoring process for a load-balancing algorithm represented by the polynomial $y^4 - y^2 - 20$. Arrange the following steps in the correct logical sequence to show how this expression is factored using the substitution method.

A facilities manager is using the polynomial $y^4 - y^2 - 20$ to model the total floor area of a modular storage complex. To factor the expression for a capacity report, the manager applies the substitution $u = y^2$. Write the resulting quadratic trinomial in terms of $u$.

An industrial analyst is documenting the algebraic simplification of a workflow efficiency model defined by the polynomial $y^4 - y^2 - 20$. To assist new trainees in identifying the specific outcomes of each stage of the substitution method, match each procedural term with its corresponding mathematical expression.

An inventory manager is using the polynomial $y^4 - y^2 - 20$ to calculate storage requirements. When factoring this expression using the substitution method, the manager should substitute $u = y^2$ to transform the expression into a standard quadratic trinomial.
