The Difference of Squares Formula: (a-b)(a+b)
In algebra, the difference of squares formula is a powerful tool used to simplify expressions and solve equations. It is a fundamental concept in mathematics, and it has numerous applications in various fields, including physics, engineering, and computer science.
What is the Difference of Squares Formula?
The difference of squares formula is given by:
(a-b)(a+b) = a^2 - b^2
This formula states that the product of two binomials, (a-b) and (a+b), is equal to the difference of the squares of a and b.
How to Apply the Formula?
The difference of squares formula can be applied in various ways to simplify expressions and solve equations. Here are a few examples:
Example 1: Simplifying an Expression
Suppose we have the expression (x-3)(x+3). Using the difference of squares formula, we can simplify this expression as follows:
(x-3)(x+3) = x^2 - 3^2 = x^2 - 9
Example 2: Solving an Equation
Suppose we have the equation (x-2)(x+2) = 0. Using the difference of squares formula, we can solve this equation as follows:
(x-2)(x+2) = x^2 - 2^2 = x^2 - 4 = 0
This equation can be solved by factoring the quadratic expression:
x^2 - 4 = (x-2)(x+2) = 0
Thus, the solutions to the equation are x = 2 and x = -2.
