Terms, Coefficients, & Like Terms

What is a constant in an expression?

• A variable that can change its value

• A fixed value that does not change, represented by a number without a variable

• An expression that contains both numbers and variables

• A mathematical operation that alters a number

Can a term be a constant?

• Yes, a constant is considered a term in an expression.

• No, a constant cannot be a term.

• Only variables can be terms, not constants.

• Constants are not used in expressions.

What does it mean to simplify an expression?

• To combine like terms and reduce it to its simplest form.

• To make the expression longer and more complex.

• To change the expression into a different variable.

• To eliminate all variables from the expression.

How do you combine like terms?

• You multiply the coefficients of terms with different variables.

• You add or subtract the coefficients of terms that have the same variable raised to the same power.

• You divide the coefficients of terms with the same variable.

• You ignore the coefficients and only focus on the variables.

What is the difference between a term and a coefficient?

• A term is a part of an expression that can include numbers and variables, while a coefficient is specifically the number that multiplies a variable within a term.

• A term is always a number, while a coefficient can be a variable.

• A term is a single number, while a coefficient is a combination of numbers and variables.

• A term is the entire expression, while a coefficient is the sum of all numbers in the expression.

What are like terms?

• Like terms are terms that have the same variable raised to the same power.

• Like terms are terms that have different variables raised to the same power.

• Like terms are terms that can be added together regardless of their variables.

• Like terms are terms that have no variables at all.

What happens if you try to combine unlike terms?

• You can combine them into a single term.

• You cannot combine unlike terms; they must remain separate in the expression.

• You can only combine them if they have the same coefficient.

• You can combine them if they are both constants.

What is the simplified form of the expression 2x + 3x + 4?
