The video tutorial reviews key algebraic vocabulary, including variables, constants, coefficients, and terms. Variables are unknowns in expressions, constants are numbers without variables, and coefficients are numbers multiplied by variables. 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?

• Constant

• Coefficient

• Variable

• Equation

What are variables in an algebraic expression?

• Fixed numbers

• Symbols of addition

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

• x and 3

• 5 and y

• x and y

• 5 and 3

What defines a constant in an algebraic expression?

• It changes with variables

• It is always zero

• It is always positive

• It has no variable attached

In the expression 5x + 8, what is the constant?

• 5x

• 5

• x

• 8

What is a coefficient in an algebraic expression?

• A constant number

• A number added to a variable

• A number multiplied by a variable

• A variable itself

In the expression 5x, what is the coefficient?

• None

• 5x

• x

• 5

How are coefficients typically written in algebraic expressions?

• After the variable

• With an addition symbol

• With a multiplication symbol

• Before the variable

What is a term in an algebraic expression?

• A part separated by addition or subtraction

• A single number

• A variable only

• A coefficient only
