Combine Like Terms

Front

What does it mean to combine like terms in an expression?

Back

Combining like terms means to simplify an expression by adding or subtracting terms that have the same variable raised to the same power.

Front

What are like terms?

Back

Like terms are terms that have the same variable and exponent. For example, 3x and 5x are like terms, while 3x and 4y are not.

Front

What is a coefficient?

Back

A coefficient is a numerical factor in a term. For example, in the term 4x, 4 is the coefficient.

Front

Identify the coefficients in the expression 2x + 3y - 5.

Back

The coefficients are 2 (for x) and 3 (for y). The -5 is a constant.

Front

What are constants in an expression?

Back

Constants are terms that do not contain any variables. For example, in the expression 4x + 5, the number 5 is a constant.

Front

Simplify the expression: 5x + 3x - 2x.

Back

The simplified expression is 6x.

Front

Combine like terms: 7y - 2 + 3y + 5.

Back

The simplified expression is 10y + 3.

Front

Can you combine the terms 2x^2 and 3x?

Back

No, you cannot combine them because they are not like terms.

Front

What is the result of combining the like terms in the expression 4a + 2b - 3a + 5b?

Back

The result is a + 7b.

Front

True or False: The expression 2x + 3y + 2x can be simplified to 4x + 3y.

Back

True.
