Here are the essential concepts you must grasp in order to answer the question correctly.
Polynomial Multiplication
Polynomial multiplication involves multiplying two or more polynomials together to form a new polynomial. This process requires distributing each term in one polynomial to every term in the other, combining like terms to simplify the result. Understanding this concept is essential for solving the given expression, as it lays the foundation for expanding the products of binomials.

Difference of Squares
The difference of squares is a specific algebraic identity that states that the product of two conjugates, such as (a + b)(a - b), equals a² - b². This concept is particularly useful in the given question, as it allows for the simplification of the expression (x + 1)(x - 1) into x² - 1, making the multiplication process more efficient.

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. This step is crucial after performing polynomial multiplication, as it helps to condense the expression into its simplest form, ensuring clarity and ease of interpretation in the final result.
