Algebra is useful because it provides tools for describing and solving problems. You can use polynomials and their properties to solve problems in engineering, communications, and economics. Properties of polynomials make it possible to find the most efficient use of time and materials.

In this chapter you will: learn to solve polynomials learn to add and subtract polynomials use polynomials to solve real-world problems learn to multiply and factor polynomials factor special cases factor trinomials learn how to solve equations by factoring learn how to choose the appropriate method for solving polynomial functions
