Unit 4b Part 2 Summative Re-take

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 find the GCF of two numbers?

Back

List the factors of each number and identify the largest factor they have in common.

Front

What is the Distributive Property?

Back

The Distributive Property states that a(b + c) = ab + ac, meaning you can distribute a number across a sum.

Front

Expand the expression using the Distributive Property: 3(4 + 5).

Back

3(4 + 5) = 3*4 + 3*5 = 12 + 15 = 27.

Front

What does it mean to factor an expression?

Back

Factoring an expression means to break it down into simpler components that, when multiplied together, give the original expression.

Front

Factor the expression: 18 + 24.

Back

The GCF is 6, so 18 + 24 = 6(3 + 4).

Front

What is an equivalent expression?

Back

An equivalent expression is a different expression that has the same value for all values of the variable.

Front

Find an equivalent expression for: 5(x + 2).

Back

5(x + 2) = 5x + 10.

Front

What is the purpose of using the GCF in factoring?

Back

Using the GCF simplifies expressions and makes them easier to work with.

Front

How do you expand an expression using the Distributive Property?

Back

Multiply the term outside the parentheses by each term inside the parentheses.
