Factoring and Simplifying Expressions

The video tutorial explains how to simplify an equation using the difference of two squares method. It begins by identifying terms that can be expressed as squares, then factors out the greatest common factor. The process continues by applying the difference of squares method to simplify the equation further, and concludes with the final factorization.

What is the first step in simplifying an expression using the difference of two squares?

• Write the expression in the form a^2 - b^2

• Identify the greatest common factor

• Multiply the terms

• Add the terms

How can the expression a^2 - b^2 be factored?

• (a + b)(a + b)

• (a - b)(a - b)

• (a + b)(a - b)

• (a^2 + b^2)
