As a data analyst reviewing a predictive model's cost function, you encounter the polynomial expression $h^4 + 4h^2 - 12$. To factor this expression efficiently using substitution, you must recall the appropriate variable assignment. Which substitution correctly rewrites this expression into a standard quadratic trinomial?

A logistics supervisor is analyzing the load capacity of a specialized shelving unit. The capacity is determined by the polynomial $h^4 + 4h^2 - 12$, where $h$ represents the height of the unit in meters. To simplify the formula for warehouse staff, the supervisor needs to factor the expression using substitution. Match each stage of the factoring process with its corresponding mathematical expression.

A quality control technician is using the polynomial $h^4 + 4h^2 - 12$ to model the heat dissipation of a new component. To simplify the formula for the production team, the technician must factor it using the substitution method. Arrange the following steps in the correct order to complete the factoring process.

An apprentice technician is following a technical manual to simplify a load-calculation formula represented by $h^4 + 4h^2 - 12$. The manual states that by using the substitution $u = h^2$, the formula can be rewritten as the quadratic trinomial $u^2 + 4u - 12$. Is this statement true or false?
