Identifying Components of Expressions

The video tutorial explains the different parts of an algebraic expression, including terms, coefficients, like terms, and constants. It provides examples to illustrate how to identify these components within expressions. The tutorial emphasizes understanding the role of coefficients as numbers working with variables and highlights the importance of recognizing like terms for combining them. Two examples are analyzed in detail to reinforce the concepts discussed.

Which of the following is NOT a part of an expression?

• Exponents

• Terms

• Coefficients

• Constants

In the expression 5x + 2, what is the term?

• 2

• 5

• x

• 5x

What is the coefficient in the term -7x?

• x

• -7

• 7

• -x

Which of the following pairs are like terms?

• 5x and 7y

• x and y

• 2 and 3

• 5x and -7x

What is a constant in an expression?

• A variable

• A number that remains the same

• A number that changes

• A coefficient

In the expression 5x + 2 - 7x - 3, how many terms are there?

• 3

• 5

• 4

• 2

In the expression 5x + 2 - 7x - 3, what are the like terms?

• 5x and 2
