Wednesday 10/14 Lesson - 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.

Front

How do you combine like terms?

Back

To combine like terms, you add or subtract the coefficients of the terms that are alike. For example, 3x + 5x = (3 + 5)x = 8x.

What is the result of X + X + X + X + X?

Back

5X

What is the result of a + a + a + a?

Back

4a

What is the result of 3 + 12c - 4c?

Back

8c + 3

Front

What is the result of 4x + 3 + 7x?

Back

11x + 3

What is the result of 2r + 2 + 5r - 2 + r?

Back

8r

Front

What is a coefficient in an algebraic expression?

Back

A coefficient is a numerical factor in a term of an algebraic expression. For example, in 5x, 5 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.

Front

What is the difference between a variable and a constant?

Back

A variable is a symbol that represents an unknown value (e.g., x, y), while a constant is a fixed value (e.g., 5, -3).
