Factorizing by Grouping Techniques

This video tutorial covers the concept of factorizing by grouping, a method used when dealing with four or more terms. The instructor explains how to group terms, identify common factors, and ensure the correct grouping by checking the resulting expressions. Advanced techniques and handling of negatives are also discussed, with multiple examples provided to illustrate each point.

What is the primary condition for using factorizing by grouping?

• When there are four or five terms

• When there are three terms

• When there is only one term

• When there are two terms

What is the first step in factorizing by grouping?

• Add all terms together

• Multiply all terms by the same number

• Divide all terms by the same number

• Group the terms into pairs

How do you determine if the grouping is done correctly?

• The grouped terms should be zero

• The grouped terms should be the same

• The grouped terms should be negative

• The grouped terms should be different

What should you do if the grouped terms are different?

• Add more terms

• Subtract terms

• Continue with the solution

• Start the question again

In the example with x squared, what is the common factor taken out?

• x

• b

• x squared

• a

What is the result when the common factor is taken out correctly?

• The terms become zero

• The terms become negative

• The terms become the same

• The terms become different

How should you handle negative terms in grouping?

• Always use a negative

• Ignore them

• Always use a positive

• Choose a positive or negative based on the situation

What is the key to ensuring the final grouped terms are correct?

• They should be zero

• They should be positive

• They should be different

• They should be the same

What should you do if the initial grouping does not work?

• Add more terms

• Start over and try a different grouping

• Subtract terms

• Ignore the mistake

In the final example, what is the common factor taken out from the first group?

• 4y

• p

• p squared

• 3
