Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Factoring and Distributing
Factoring involves breaking down expressions into simpler components, while distributing refers to applying the distributive property to multiply terms. In this case, we need to distribute (x - y) across the polynomial (x^2 + xy + y^2) to find the product. Understanding how to apply these operations is crucial for simplifying algebraic expressions.

Polynomial Multiplication
Polynomial multiplication involves multiplying two or more polynomials together, which can result in a new polynomial. Each term in the first polynomial must be multiplied by each term in the second polynomial, and like terms are then combined. This concept is essential for solving the given problem, as it requires careful multiplication of the terms.

Combining Like Terms
Combining like terms is the process of simplifying an expression by adding or subtracting terms that have the same variable raised to the same power. After distributing and multiplying the polynomials, it is important to identify and combine any like terms to arrive at the final simplified expression. This step is key to presenting the product in its simplest form.
