Combining Like Terms part 2

Front

What are like terms?

Back

Like terms are terms that have the same variable raised to the same power. For example, 3xy and 5xy are like terms, while 3xy and 4x^2 are not.

Front

How do you combine like terms?

Back

To combine like terms, add or subtract the coefficients of the terms that are alike. For example, in 3x + 5x, you combine them to get 8x.

Front

What is the first step in simplifying an expression?

Back

The first step is to identify and group like terms together.

Front

Simplify: 8xy + 7x^2 + 6y - 4x^2 - 5xy

Back

3x^2 + 3xy + 6y

Front

Simplify: 10x + 15 + 3x + 2

Back

13x + 17

Front

Simplify: 13 + 6k + 11k - 10

Back

3 + 17k

Front

Simplify: 5a + 2b - 3a + 4

Back

2a + 2b + 4

Front

Simplify: 7v + 2 + 12 + 2v

Back

9v + 14

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 does it mean to simplify an expression?

Back

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