Ill give points, and how can the operations of polynomials be used to create new polynomial models? provide real-world examples of when it is necessary to add, subtract, multiply, or compose polynomials to get a new polynomial that model real situations.

Just as you can perform the four operations on polynomials with one variable, you can add, subtract, multiply, and divide polynomials with more than one variable. The process is exactly the same, but you have more variables to keep track of. When you are adding and subtracting polynomials with more than one variable, you have to pay particular care to combining like terms only. When you multiply and divide, you also need to pay particular attention to the multiple variables and terms. You can multiply and divide terms that aren’t like, but to add and subtract terms they must be like terms

Polynomials are algebraic expressions that are created and used by people every day for numerous purposes. For example, someone designing a pool  would use polynomials to model the curves, ... You can add, subtract and multiply terms in a polynomial just as you do division by a variable
