Subtracting from
To subtract from , first write the subtraction expression:
Next, distribute the subtraction by multiplying each term in the second polynomial by , which changes their signs:
Rearrange the terms to group the like terms together:
Finally, combine the like terms. The terms cancel out:
The difference is .

As part of developing an automated financial tracking tool, you are required to document the exact algebraic steps taken to subtract the old cost model, , from the new baseline model, . Recall the standard procedure for polynomial subtraction and arrange the computational steps in the correct operational order.
A logistics company uses two different models to estimate operational costs. Model A is represented by the polynomial , and Model B is represented by . If an analyst subtracts Model B from Model A to find the difference, which simplified expression represents the result?
A corporate data analyst is verifying the sign changes in a financial model used for budget forecasting. The model requires subtracting the 'Expense Projection' polynomial from the 'Revenue Baseline' polynomial . Match each original term from the Expense Projection polynomial with its correct form after the subtraction sign has been distributed (but before combining like terms).
In a corporate financial forecasting tool, the efficiency variance is calculated by subtracting the 'Operational Risk' polynomial from the 'Planned Revenue' polynomial . During the algebraic process of subtracting these two polynomials, the distributive property is applied to the 'Operational Risk' polynomial, which results in the term becoming positive.
An inventory analyst is auditing a database formula and must subtract the 'Shrinkage' model, , from the 'Total Stock' model, . Recalling the proper algebraic rules for polynomial subtraction, the analyst begins by distributing the subtraction operation. This step is performed by multiplying each term in the 'Shrinkage' model by ____, which correctly changes their signs before combining like terms.
