How to factor using the grouping method

The video tutorial covers the process of factoring algebraic expressions, starting with an introduction to the concept and initial steps. It then explores various factoring methods, including difference of squares, difference of cubes, factoring trinomials, and factoring by grouping. The focus is on factoring by grouping, especially for expressions with four terms. The tutorial demonstrates how to group terms, factor out the greatest common factor (GCF), and ensure the expressions in parentheses are identical for successful factoring.

Which of the following is NOT a factoring method discussed in the video?

• Factoring by substitution

• Difference of cubes

• Factoring by grouping

• Difference of squares

When should you consider using the factoring by grouping method?

• When the expression is a perfect square

• When the expression is a trinomial

• When the expression has four terms

• When the expression has two terms

What is the first step in the factoring by grouping method?

• Group the first two terms and the last two terms

• Rearrange the terms randomly

• Factor out the GCF from the entire expression

• Factor out a common binomial

Why is it important to ensure the expressions in the parentheses are identical?

• To simplify the expression

• To allow for further factoring

• To make the expression a perfect square

• To check for errors

In the example given, what is factored out from the expression to achieve identical parentheses?

• A variable

• A negative one

• A positive one

• A constant
