Polynomials: Solving Equations and Multiplying
The exponents that you learned about in the previous hour are powerful—no pun intended—and they allow you to work with algebra problems that are quite complex. Don’t forget that they are efficient, as they help make lengthy multiplication expressions very compact.
You can now add and subtract polynomials that include exponents. You can also multiply monomials to get a simplified answer and raise monomials to powers. In this hour, you learn about multiplying polynomials by monomials and by other polynomials, and how polynomials can be used to solve word problems. First, let’s combine your knowledge of polynomials with basic equation skills to solve some new equations.
