Introduction: Delving into Algebraic Expressions

In the realm of mathematics, algebraic expressions serve as the building blocks for more complex equations and formulas. Understanding algebraic expressions is crucial for students, engineers, and anyone involved in quantitative fields. This article aims to dissect and simplify the given expression: 6(x²-1) ⋅ (6x-1) / 6(x+1). We will explore each component, apply algebraic principles, and arrive at a simplified form, making it easier to understand and work with. Our primary goal is not just to simplify the expression but also to elucidate the underlying mathematical concepts, thereby enhancing your comprehension and skills in algebra. The process involves factoring, canceling common terms, and applying the distributive property, all of which are fundamental techniques in algebraic manipulation. By breaking down the expression into manageable parts, we can appreciate how each element contributes to the overall structure and value. This approach not only helps in solving this particular problem but also equips you with a versatile toolkit for tackling similar challenges in the future.

Breaking Down the Expression: A Step-by-Step Approach

To effectively simplify the expression, we must first break it down into its constituent parts. The expression 6(x²-1) ⋅ (6x-1) / 6(x+1) comprises several key components that warrant individual attention. First, we have the quadratic term (x²-1), which is a difference of squares and can be factored. Next, we have the linear term (6x-1), which represents a straightforward algebraic expression. The numerator also includes a constant multiplier, 6, which affects the overall value of the expression. In the denominator, we find 6(x+1), another linear term multiplied by a constant. Each of these parts plays a crucial role in the expression's behavior and simplification. By examining each term individually, we can identify opportunities for factoring, cancellation, and simplification. For instance, recognizing (x²-1) as a difference of squares allows us to factor it into (x+1)(x-1), which is a crucial step in simplifying the entire expression. Similarly, the presence of the constant 6 in both the numerator and the denominator suggests a possible cancellation. This methodical approach ensures that we don't overlook any potential simplifications and that we handle the expression with precision.

Factoring the Difference of Squares: x²-1

The term x²-1 is a classic example of the difference of squares, a fundamental concept in algebra. The difference of squares factorization is based on the formula a² - b² = (a + b)(a - b). In our case, x²-1 can be seen as x² - 1², where a = x and b = 1. Applying the formula, we can factor x²-1 into (x + 1)(x - 1). This factorization is a pivotal step in simplifying the given expression because it introduces a term, (x + 1), that also appears in the denominator. Recognizing and applying this factorization technique is essential for simplifying many algebraic expressions and solving equations. The ability to identify patterns like the difference of squares is a cornerstone of algebraic proficiency. It allows us to transform complex expressions into simpler, more manageable forms. By factoring x²-1, we've taken a significant step towards simplifying the entire expression and revealing its underlying structure. This step highlights the importance of mastering fundamental algebraic identities and their applications.

Rewriting the Expression: Incorporating the Factored Form

Now that we've factored x²-1 into (x + 1)(x - 1), we can rewrite the original expression. Substituting the factored form into the expression 6(x²-1) ⋅ (6x-1) / 6(x+1), we get 6(x + 1)(x - 1) ⋅ (6x-1) / 6(x+1). This rewritten expression highlights the common factors in the numerator and the denominator, which can be canceled out to further simplify the expression. The process of rewriting an expression with factored terms is a crucial technique in algebra because it often reveals hidden simplifications. By expressing terms in their factored form, we make it easier to identify common factors that can be eliminated, leading to a more concise and manageable expression. In this case, the factored form clearly shows the presence of (x + 1) in both the numerator and the denominator, setting the stage for the next simplification step. Rewriting the expression is not just a cosmetic change; it's a strategic move that unlocks the potential for simplification and makes the expression easier to analyze and manipulate.

Canceling Common Factors: Simplifying the Fraction

In the rewritten expression 6(x + 1)(x - 1) ⋅ (6x-1) / 6(x+1), we can observe several common factors between the numerator and the denominator. Specifically, the constant 6 and the term (x + 1) appear in both. Canceling these common factors is a fundamental algebraic operation that simplifies the expression significantly. When we cancel the 6 in both the numerator and the denominator, we reduce the expression to (x + 1)(x - 1) ⋅ (6x-1) / (x+1). Further, we can cancel the (x + 1) term from both the numerator and the denominator, provided that x ≠ -1 (since division by zero is undefined). This cancellation leaves us with (x - 1) ⋅ (6x-1), a much simpler form of the original expression. The process of canceling common factors is based on the principle that dividing both the numerator and the denominator of a fraction by the same non-zero quantity does not change the value of the fraction. This technique is a cornerstone of algebraic simplification and is essential for solving equations and working with rational expressions. By canceling common factors, we strip away unnecessary complexity and reveal the underlying structure of the expression.

Applying the Distributive Property: Expanding the Expression

After canceling common factors, we are left with the expression (x - 1) ⋅ (6x-1). To further simplify this, we need to apply the distributive property, which states that a(b + c) = ab + ac. In our case, we will distribute (x - 1) across (6x-1). This means we multiply each term in the first binomial by each term in the second binomial. The process unfolds as follows: x * 6x = 6x², x * -1 = -x, -1 * 6x = -6x, and -1 * -1 = 1. Combining these terms, we get 6x² - x - 6x + 1. Now, we can combine like terms, which are the terms with the same variable and exponent. In this case, -x and -6x are like terms. Adding them together, we get -7x. Thus, the expression simplifies to 6x² - 7x + 1. The distributive property is a fundamental algebraic tool that allows us to expand expressions and remove parentheses. It is essential for simplifying expressions, solving equations, and performing various algebraic manipulations. By applying the distributive property, we transform a product of binomials into a trinomial, which is often easier to work with in subsequent steps. This step highlights the importance of mastering basic algebraic techniques for simplifying complex expressions.

Final Simplified Form: 6x² - 7x + 1

After applying the distributive property and combining like terms, we arrive at the final simplified form of the expression: 6x² - 7x + 1. This quadratic expression is the result of simplifying the original expression 6(x²-1) ⋅ (6x-1) / 6(x+1). The simplified form is much easier to understand and work with compared to the original expression. It clearly shows the quadratic nature of the expression and its coefficients. This process of simplification underscores the power of algebraic manipulation in transforming complex expressions into simpler, more manageable forms. The ability to simplify expressions is crucial in various mathematical contexts, including solving equations, graphing functions, and performing calculus operations. By reducing an expression to its simplest form, we gain a clearer understanding of its properties and behavior. The final simplified form, 6x² - 7x + 1, represents the culmination of our step-by-step simplification process, highlighting the importance of each technique we employed, from factoring to canceling common factors to applying the distributive property.

In conclusion, simplifying the expression 6(x²-1) ⋅ (6x-1) / 6(x+1) to its final form 6x² - 7x + 1 demonstrates the power and importance of algebraic simplification. We began by breaking down the expression into its components, factored the difference of squares, canceled common factors, and applied the distributive property. Each step was crucial in transforming the complex original expression into a simpler, more manageable quadratic expression. This process not only provides a solution but also reinforces fundamental algebraic principles and techniques.
