Front

What is the Greatest Common Factor (GCF)?

Back

The GCF is the largest number that divides two or more numbers without leaving a remainder.

Front

How do you factor an algebraic expression using the GCF?

Back

To factor an algebraic expression using the GCF, identify the largest common factor of the coefficients and variables, then divide each term by the GCF and express the original expression as the product of the GCF and the resulting expression.

Front

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

Back

Combining like terms means to add or subtract terms that have the same variable raised to the same power.

Front

What is an equivalent expression?

Back

An equivalent expression is one that has the same value for all values of the variable(s) involved.

Front

How do you evaluate an expression with given values for variables?

Back

To evaluate an expression, substitute the given values for the variables and perform the arithmetic operations.

Front

What is the process to find the GCF of two numbers?

Back

To find the GCF, list the factors of each number, then identify the largest factor that appears in both lists.

Front

What is the Least Common Multiple (LCM)?

Back

The LCM is the smallest number that is a multiple of two or more numbers.

Front

How can you determine if two expressions are equivalent?

Back

You can determine if two expressions are equivalent by simplifying both expressions and checking if they result in the same expression.
