How to determine if an expression is a monomial, binomial, or trinomial

The video tutorial explains how to determine if an expression is a monomial, binomial, trinomial, or polynomial. It provides definitions for each type and demonstrates the process of identifying the type of a given expression. The example used shows that 3/7 * X is a monomial because it involves the multiplication of a number and a variable, with no addition involved.

What is a monomial?

• A number, a variable, or the multiplication of a number and one or more variables to a positive exponent

• The addition of three monomials

• The addition of two or more monomials

• The addition of two monomials

Which of the following is true about a binomial?

• It is the addition of two monomials

• It is a single term

• It is the addition of three monomials

• It is the addition of four monomials

If an expression has no addition, what can it not be classified as?

• Trinomial

• Binomial

• Polynomial

• Monomial

How can you identify a monomial in an expression?

• By identifying multiplication of a number and a variable

• By finding subtraction of terms

• By finding addition of terms

• By identifying division of terms

In the expression 3/7 * X, what does 3/7 represent?

• A coefficient

• A variable

• An exponent

• A constant
