Classifying Polynomials: Key Concepts and Techniques

Mr. Lee introduces polynomials, explaining their definitions, terms, and types, such as monomials, binomials, and trinomials. He discusses the degree and leading coefficient of polynomials and provides examples of non-polynomial expressions. The video also covers how to identify polynomial features and arrange them in standard form.

Which of the following is an example of a monomial?

• 5x^3

• 1/y^2

• x^2 - 4

• x^2 - 4x + 1

What must be true for an expression to be considered a monomial?

• It must have at least two terms.

• It must include a fraction.

• All exponents must be positive.

• It must have a variable in the denominator.

What is the term used to describe each separate monomial in a polynomial?

• Term

• Exponent

• Coefficient

• Degree
