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: a monomial is a number, variable, or their product with a positive exponent; a binomial is the sum of two monomials; a trinomial is the sum of three monomials; and a polynomial is the sum of two or more monomials. The tutorial then demonstrates identifying a monomial by checking for multiplication without addition, using the example of 3/7 * X.

What is a monomial?

• The addition of two or more monomials

• The addition of two monomials

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

• The addition of three monomials

Which of the following is a binomial?

• The addition of two monomials

• The multiplication of a number and a variable

• The addition of three monomials

• A single variable

How can you determine if an expression is not a polynomial?

• By checking if there is any multiplication

• By checking if there is any addition

• By checking if there is any division

• By checking if there is any subtraction

What is the expression 3/3 times X / 7 equivalent to?

• 3 * X / 7

• X / 3/7

• 3/7 * X

• 7/3 * X

Why is the expression 3/7 * X considered a monomial?

• Because it is the multiplication of a number by a variable

• Because it is the division of a number by a variable

• Because it involves subtraction

• Because it involves addition
