What is a constant in an algebraic expression?

Back

A constant is a fixed value that does not change. For example, in the expression 15n - 4, -4 is a constant.

What are the terms in the expression -4x + 6y - 2?

Back

The terms are -4x, 6y, and -2.

Front

True or False: Fractions, like 5/8, are considered constants.

Back

True. Fractions are fixed values and can be considered constants.

What is a coefficient in an algebraic expression?

Back

A coefficient is a numerical factor that multiplies a variable. For example, in 15n - 4, 15 is the coefficient of n.

Front

What are the variables in the expression -4x + 6y - 2?

Back

The variables are x and y.

Front

What is an algebraic expression?

Back

An algebraic expression is a combination of numbers, variables, and operations. For example, 3x + 5 is an algebraic expression.

Front

What is the difference between a term and a factor?

Back

A term is a single part of an expression, while a factor is a number or variable that multiplies with others. For example, in 3xy, 3, x, and y are terms, and 3 is a factor.

Front

What does it mean to simplify an algebraic expression?

Back

To simplify an algebraic expression means to combine like terms and reduce it to its simplest form.

Front

What are like terms?

Back

Like terms are terms that have the same variable raised to the same power. For example, 2x and 3x are like terms.

Front

What is the degree of an algebraic expression?

Back

The degree of an algebraic expression is the highest power of the variable in the expression. For example, in 4x^3 + 2x^2, the degree is 3.
