Exploring Algebra 2 Concepts and Techniques

The video tutorial covers topics from the Algebra 2 curriculum, focusing on factoring techniques. It begins with an introduction to the importance of these topics for preparing for exams. The tutorial is divided into units, with Unit 1 focusing on factoring. Various methods are discussed, including pulling out the greatest common factor, factor by grouping, and trinomial factoring using substitution. The video provides step-by-step examples to illustrate each method, helping students understand how to apply these techniques to different algebraic expressions.

What is the first step in factoring a polynomial?

• Extract the greatest common factor

• Identify the leading coefficient

• Combine like terms

• Set up two sets of parentheses

When factoring a trinomial with a leading coefficient of one, what method is used?

• Quadratic formula

• AM method

• Difference of squares

• Greatest common factor

Which of the following is a perfect square?

• 6

• 4

• 2

What is the result of factoring x^2 - 9?

• (x + 2)(x - 2)

• (x + 1)(x - 1)

• (x + 9)(x - 9)
