Introduction

Algebra is a branch of mathematics that deals with the study of mathematical symbols, equations, and formulas. It is a powerful tool used to solve equations, manipulate expressions, and model real-world problems. One of the fundamental concepts in algebra is the special product formula for the "square of a sum," which is given by the equation $$(A+B)^2 = A^2 + 2AB + B^2$$. In this article, we will explore the significance of this formula, its applications, and how it can be used to simplify complex expressions.

What is the Special Product Formula?

The special product formula for the "square of a sum" is a mathematical formula that allows us to expand the square of a binomial expression. It is a fundamental concept in algebra that is used to simplify complex expressions and solve equations. The formula is given by $$(A+B)^2 = A^2 + 2AB + B^2$$.

How Does the Formula Work?

To understand how the formula works, let's consider an example. Suppose we want to expand the expression $$(3x + 6)^2$$. Using the special product formula, we can expand it as follows:

(3x + 6)^2 = (3x)^2 + 2(3x)(6) + 6^2

Using the formula, we can simplify the expression as follows:

(3x + 6)^2 = 9x^2 + 36x + 36

As we can see, the special product formula allows us to expand the square of a binomial expression in a simple and efficient way.
