Understanding Algebraic Expressions

The video tutorial reviews key algebraic vocabulary, including variables, constants, coefficients, and terms. Variables are unknowns in expressions, constants are numbers without variables, coefficients are numbers multiplied by variables, and terms are parts of equations separated by addition or subtraction symbols. The tutorial emphasizes the importance of understanding these concepts for solving algebraic problems.

Which of the following is NOT a key algebraic term introduced in the video?

• Coefficient

• Variable

• Equation

• Constant

What are variables in an algebraic expression?

• Fixed values

• Symbols of addition

• Known numbers

• Unknown quantities

In the expression 5x + 3y + 8, which are the variables?

• 5 and 3

• 5x and 3y

• x and y

• 8

What defines a constant in an algebraic expression?

• A variable without a number

• A number without a variable

• A number with a variable

• A symbol of addition

In the expression 5x + 3y + 8, which number is the constant?

• 5

• x

• 3

• 8

What is a coefficient in an algebraic expression?

• A variable without a number

• A number multiplied by a variable

• A number added to a variable

• A constant value

In the expression 5x + 3y, what are the coefficients?

• 5 and 3

• x and y
