Factoring Binomials and Basic Operations

This lesson focuses on factoring binomials that are the difference of two perfect squares, specifically when the coefficient of x squared is 25. The process involves setting up two sets of parentheses, ensuring both the coefficient and the other term are perfect squares. The square roots of these terms are placed in specific positions within the parentheses, with a plus sign in one and a minus sign in the other, resulting in the factors of the expression.

What is the main focus of this lesson?

• Graphing linear equations

• Solving quadratic equations

• Factoring binomials that are the difference of two perfect squares

• Factoring trinomials
