~ Combining Like-Terms ~

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, while 3x and 4y are not.

How do you combine like terms?

Back

To combine like terms, add or subtract the coefficients of the terms that have the same variable. For example, 3x + 5x = (3 + 5)x = 8x.

Simplify: n - 10 + 9n - 3

Back

10n - 13

Front

Simplify: 22n + 15 + 1 - 23n

How many terms are in the expression: 2x + 5 - x + 6x + 1?

Back

5 terms

Front

Simplify: -7 + 5x - 3x - 12x

Back

-10x - 7

Front

What is a coefficient?

Back

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

Front

What is a constant term?

Back

A constant term is a term that does not contain any variables. For example, in the expression 3x + 5, 5 is the constant term.

What does it mean to simplify an expression?

Back

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