Factorizing a2 2ab2 b2 - c2: A Comprehensive Guide

Understanding the process of factorization is crucial for solving complex algebraic expressions. In this article, we will demonstrate how to factorize the expression a2 2ab2 b2 - c2. This guide is designed for students, educators, and anyone interested in enhancing their algebraic skills.

Understanding the Expression

The given expression is a2 2ab2 b2 - c2. At first glance, the expression might appear complex, but a careful breakdown will reveal its components.

Identifying the Perfect Square Trinomial

The key to factoring this expression lies in recognizing that some parts of the expression form a perfect square trinomial. Specifically, the terms a2 and 2ab and b2 form the perfect square trinomial a2 2ab b2.

Rewriting the Expression

By recognizing the perfect square trinomial, we can rewrite the initial expression as follows:

a2   2ab2   b2 - c2 a2   2ab   b2 - c2 - ab2

Factoring the Perfect Square Trinomial

The expression a2 2ab b2 can be rewritten as (a b)2. Therefore, the expression becomes:

(a   b)2 - c2 - ab2

Further Simplification

Now, observe that the expression is no longer a perfect square trinomial. However, we can still simplify the equation by consolidating like terms. Recognize that the term -ab2 does not factor out directly but can be integrated into the expression for further simplification.

Applying the Difference of Squares Formula

The remaining expression, (a b)2 - c2, can be simplified further using the difference of squares formula, which states:

a2 - b2  (a   b)(a - b)

Thus, the expression can be factored as:

(a   b)2 - c2 (a   b   c)(a   b - c)

Final Factored Form

After the simplification, the final factored form of the expression a2 2ab2 b2 - c2 is:

(a   b   c)(a   b - c)

Conclusion

By breaking down the expression into simpler components and applying algebraic principles, we have successfully factored the given expression. The process of recognizing perfect square trinomials and the difference of squares formula is key to solving such equations efficiently.
