Intro to Combine Like terms with Algebra tiles

Front

What does it mean to combine like terms in algebra?

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 is a like term?

Back

A like term is a term that has the same variable and exponent as another term. For example, 3x and 5x are like terms.

Front

What is the simplified form of the expression 2x + 3x?

Back

5x

Front

What is the simplified form of the expression 4x + 4?

Back

4x + 4 cannot be simplified further because the terms are not like terms.

Front

What is the purpose of algebra tiles?

Back

Algebra tiles are a visual tool used to help students understand and manipulate algebraic expressions and equations.

Front

How do you represent the term 6x using algebra tiles?

Back

You would use 6 tiles representing 'x' to show the term 6x.

Front

What is the simplified form of the expression 4x + 3x?

Back

7x

Front

What does the expression x^2 + 2x represent in terms of algebra tiles?

Back

It represents 1 tile for x^2 and 2 tiles for x.

Front

What is the value of the expression 7x when x = 2?

Back

14 (because 7 * 2 = 14).

Front

What is the difference between a constant and a variable in algebra?

Back

A constant is a fixed value (like 5), while a variable is a symbol that represents an unknown value (like x).
