What's a Term in a Polynomial?
Polynomials are those expressions that have variables raised to all sorts of powers and multiplied by all types of numbers.
When you work with polynomials you need to know a bit of vocabulary, and one of the words you need to feel comfortable with is "term".
So check out this tutorial, where you'll learn exactly what a "term" in a polynomial is all about.
Types of Polynomials
The following lesson looks at the different types of polynomials: monomials, binomials and trinomials.
