The "Difference of Squares" is a mathematical concept that refers to the expression formed by subtracting one square number from another. It can be represented as a² - b², where a and b are any real numbers. This expression can be factored into the product of two binomials: a² - b² = (a + b)(a - b). This property is useful in algebra for simplifying expressions and solving equations. This concept is often applied in various areas of mathematics, including algebra and calculus. It helps in factoring polynomials and can be used to solve quadratic equations more efficiently. Understanding the Difference of Squares is essential for students as it lays the groundwork for more advanced mathematical concepts.
