In 1–2 sentences, describe a scenario in which you might need to use the difference of two squares identity

to find the product of two numbers. First describe the general mathematical conditions and explain how you would find x and a. Then provide a specific, real-world scenario.

One might need to use the difference of two squares identity to find the product of two numbers when the numbers can be expressed as (x+a)(x-a), with x representing the middle term and a being the square root of the difference of the squares. For example, in architecture, when calculating the area of a rectangular garden surrounded by a pathway with a width of a, by subtracting the area of the smaller rectangle (x-a) from the area of the larger rectangle (x+a), we can find the total area of the garden.

The difference of two squares identity (a^2 - b^2 = (a + b)(a - b)) can be used to find the product of two numbers when they are the square of two different terms. To find x and a, you would need to identify the perfect square numbers that make up the given expression. As a real-world scenario, imagine finding the total area of a rectangular garden by multiplying the difference of two square lengths, with each square representing the lengths of two adjacent sides of the garden.
