The video tutorial explains how to identify polynomials by understanding that they are sums of monomials. It emphasizes the importance of checking each term to ensure it is a monomial, which requires that exponents are not negative or rational. The tutorial provides examples to illustrate the process of determining if an expression is a polynomial.

What is a polynomial?

• The sum of one or more monomials

• A single number

• A fraction

• A product of two numbers

Which of the following is NOT a criterion for a term to be a monomial?

• The term is a constant

• The exponent is not rational

• The term is a fraction

• The exponent is not negative

What should you check to determine if an expression is a polynomial?

• If all terms are constants

• If all terms are products

• If all terms are monomials

• If all terms are fractions

In the given example, why is the expression considered a polynomial?

• Because it has a rational exponent

• Because it has a negative exponent

• Because it is a single number

• Because all terms are monomials

What is the significance of the number 3 in the example?

• It is a monomial

• It is not a monomial

• It is a fraction

• It is a negative number
