## Difference of Two Squares Calculator

n mathematics, the difference of two squares is an expression that can be simplified using the algebraic identity:

``````a^2 - b^2 = (a + b)(a - b)
``````

Where:

• a and b can be any real numbers or expressions

This identity is known as the difference of squares factorization and is a fundamental concept in algebra. It allows us to factor quadratic expressions and simplify other algebraic expressions.

## Formulae and Applications

The difference of squares factorization has various applications in mathematics and other fields. Here are some examples:

1. Factoring Quadratic Expressions: The difference of squares factorization can be used to factor quadratic expressions of the form x^2 – ay^2, where a is a constant. For instance, we can factor x^2 – 4y^2 as (x + 2y)(x – 2y).
2. Simplifying Expressions: The difference of squares factorization can simplify other algebraic expressions. For example, we can simplify the expression (x + 2)(x – 5) by using the difference of squares identity:`(x + 2)(x - 5) = x^2 - 3x - 10`
3. Solving Quadratic Equations: The difference of squares factorization can be used to solve quadratic equations of the form ax^2 + bx + c = 0, where a, b, and c are constants. For instance, we can solve the equation x^2 – 6x + 9 = 0 by factoring it as (x – 3)(x – 3) and setting each factor equal to zero.
