Pre-Algebra: Coefficients, Constants, Terms and Like Terms

Front

What is a coefficient in an algebraic expression?

Back

A coefficient is a numerical factor that multiplies a variable in an algebraic expression. For example, in 5x, 5 is the coefficient.

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 + 4, 4 is the constant.

Front

What are terms in an algebraic expression?

Back

Terms are the parts of an expression separated by addition or subtraction. For example, in 2x + 3y - 5, the terms are 2x, 3y, and -5.

Front

What are like terms?

Back

Like terms are terms that have the same variable raised to the same power. For example, 3x and 5x are like terms, but 3x and 4y are not.

Front

Simplify: 2x + 3x

Back

5x

Front

Simplify: 4y - 2y + 3y

Back

5y

Front

Combine the like terms: 7a + 2b - 3a + 4b

Back

4a + 6b

Front

Are 5x^2 and 5x like terms?

Back

No, they are not like terms because they have different exponents.

Front

Evaluate: If x = 3, what is 4x + 2?

Back

14

Front

What is the result of combining like terms: 6m - 2m + 4n - 3n?

Back

4m + n
