Factoring Blitz # 2 - Factoring by grouping - Online Tutor

The video tutorial explains how to factor algebraic expressions by grouping, focusing on cases with four terms. It covers the process of identifying common factors and factoring them out, using examples to illustrate the steps. The tutorial also discusses advanced techniques for grouping terms and emphasizes the importance of checking the results.

What is the first step when you encounter four terms in a polynomial?

• Simplify each term individually

• Apply the binomial theorem

• Factor by grouping

• Use the quadratic formula

When factoring by grouping, what should you do if the terms do not share a common factor?

• Rearrange the terms

• Use a different factoring method

• Skip the problem

• Factor out the greatest common factor

How can you verify that your factoring by grouping is correct?

• Use a calculator

• Ensure all terms are positive

• Check if the product of the factors equals the original expression

• Count the number of terms

What should you do if the terms in a polynomial are interchanged?

• Ignore the order

• Re-group them to find common factors

• Use the quadratic formula

• Divide by the highest coefficient

In the example given, what common expression is factored out from the grouped terms?

• X^2 + 3

• X + 1

• X + 5

• A + B
