Conclusion

In this chapter, you have reviewed a number of activities relating to polynomial expressions. A polynomial expression consists of a monomial expression or two or more monomial expressions combined through operations involving addition or subtraction. When you work with polynomials, it helps to be able to distinguish them according to whether they are binomials. Among commonly used binomials are those that involve squares or the sum and difference of the same terms. In addition to using standard equations to work with such binomials, you can also use the FOIL approach. This approach allows you to quickly combine terms. For polynomials involving several variables, you can use forms of multiplication and division derived from arithmetic. When you perform operations of these types, it is important to order the terms of the polynomials according to the degrees of their exponents.
