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 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.
