Do you often find yourself struggling with algebraic expressions and equations? Are you looking for a comprehensive guide to understanding and simplifying complex mathematical formulas? If so, you're in the right place. In this blog post, we will delve into the expanded form of (A+B-C)² and provide you with a step-by-step guide to simplify this algebraic expression.

Understanding the Algebraic Expression

Before we dive into the simplification process, let's first understand the components of the algebraic expression (A+B-C)². This expression consists of three terms: A, B, and C. The operation being performed is addition and subtraction, along with the exponentiation of ².

Step-by-Step Simplification Process

To expand and simplify the expression (A+B-C)², we need to follow a series of steps to remove the brackets and perform the necessary operations. Let's break down the process into manageable steps:

Step 1: Expand the Square

The first step is to expand the square of the expression. To do this, we apply the formula (x+y)² = x² + 2xy + y². In our case, x = A, y = B-C. Therefore, the expansion of (A+B-C)² is:

(A+B-C)² = A² + 2A(B-C) + (B-C)²

Step 2: Simplify the Terms

Next, we simplify the terms by expanding the expressions within the brackets. This results in:

(A+B-C)² = A² + 2AB - 2AC + B² - 2BC + C²

Step 3: Combine Like Terms

Finally, we combine the like terms to further simplify the expression:

(A+B-C)² = A² + B² + C² + 2AB - 2AC - 2BC

Conclusion

In conclusion, the expanded form of (A+B-C)² is A² + B² + C² + 2AB - 2AC - 2BC. By following the step-by-step simplification process outlined above, you can easily expand and simplify complex algebraic expressions.
