Parts of An Algebraic Expression

Front

What is a constant in an algebraic expression?

Back

A constant is a fixed value that does not change. For example, in the expression 3x + 2y + 7, the constant is 7.

Front

What is a coefficient in an algebraic expression?

Back

A coefficient is a numerical factor that multiplies a variable. For example, in the expression 6y + 7, the coefficient of y is 6.

Front

Identify the coefficient in the expression 4x + 5.

Back

The coefficient is 4.

Front

What is a variable in an algebraic expression?

Back

A variable is a symbol that represents an unknown value. For example, in the expression 3x + 2, x is the variable.

Front

How is the number 9 described in the expression 9m + 3n + 4?

Back

The number 9 is a coefficient.

Front

Identify the constant in the expression 4y + 2 + x.

Back

The constant is 2.

Front

What is a term in an algebraic expression?

Back

A term is a single mathematical expression that can be a number, a variable, or a combination of both. For example, in 3x + 4y + 5, the terms are 3x, 4y, and 5.

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 in an algebraic expression?

Back

Like terms are terms that have the same variable raised to the same power. For example, 3x and 5x are like terms.

Front

What is the difference between an expression and an equation?

Back

An expression is a combination of numbers, variables, and operations without an equality sign, while an equation states that two expressions are equal.
