Learn how to factor by grouping

The video tutorial explains how to identify and divide out a common factor, specifically X-1, from algebraic terms. It demonstrates the process of dividing both terms by X-1 and shows the resulting expression in parentheses. The tutorial concludes with a brief summary of the steps involved.

What is the common factor shared by the terms in the expression?

• X / 1

• X * 1

• X - 1

• X + 1

What is the purpose of dividing out the common factor from both terms?

• To change the variable

• To add more terms

• To make the expression more complex

• To simplify the expression

What operation is performed on both terms to simplify the expression?

• Subtraction

• Division

• Addition

• Multiplication

After dividing out the common factor, what remains in the expression?

• 3 + X

• 3 - X

• X - 1

• X + 1

What is placed in parentheses after dividing out the common factor?

• 3 + X

• X - 1

• X + 1

• 3 - X
