Understanding the Expression

In this mathematical problem, we are tasked with simplifying the algebraic expression 6(1+8x). This expression involves the product of a constant term, 6, and a binomial, (1+8x). Simplifying such expressions is a fundamental skill in algebra, and it often involves applying the distributive property. The distributive property is a key concept in mathematics that allows us to multiply a single term by each term inside a set of parentheses. Mastering this skill is crucial for solving more complex algebraic equations and problems. This initial step of understanding the structure of the expression sets the stage for the application of algebraic principles to achieve simplification. Without this foundational comprehension, the subsequent steps may not be as clear, potentially leading to errors in the process. Understanding the expression also helps in identifying the specific operations that need to be performed and the order in which they should be carried out. In this case, the presence of parentheses indicates the need to apply the distributive property, which will be discussed in detail in the following sections.

Applying the Distributive Property

The distributive property is the core principle we'll use to simplify 6(1+8x). This property states that for any numbers a, b, and c, a(b + c) = ab + ac. In simpler terms, it means we multiply the term outside the parentheses by each term inside the parentheses. Applying this to our expression, we multiply 6 by both 1 and 8x. This results in 6 * 1 + 6 * 8x, which simplifies to 6 + 48x. This step is crucial because it removes the parentheses, allowing us to combine like terms if necessary. The distributive property is a cornerstone of algebraic manipulation, and its correct application is essential for arriving at the simplified form of the expression. The ability to distribute accurately ensures that all terms within the parentheses are correctly accounted for, preventing errors in the final result. By meticulously applying this property, we break down the complex expression into simpler components, making it easier to manage and further simplify if needed. In this specific instance, the distributive property enables us to transform the initial expression into a more manageable form that can be easily understood and evaluated.

Step-by-Step Simplification

Let's break down the simplification of 6(1+8x) step-by-step to ensure clarity.

  1. Identify the terms: We have 6 outside the parentheses and (1+8x) inside the parentheses. The term 6 is the constant that we will distribute across the binomial (1+8x).
  2. Apply the distributive property: Multiply 6 by each term inside the parentheses:
    • 6 * 1 = 6
    • 6 * 8x = 48x
  3. Combine the results: Add the results from step 2: 6 + 48x.

Therefore, the simplified expression is 6 + 48x. Each step in this process is designed to methodically transform the initial expression into its simplest form. By breaking down the problem into smaller, manageable steps, we minimize the risk of errors and enhance the clarity of the solution. The initial identification of terms sets the stage for the application of the distributive property, which is the pivotal step in this simplification. The subsequent combination of results ensures that all terms are accounted for and that the expression is presented in its most concise form. This step-by-step approach is not only effective for solving this specific problem but also provides a framework for tackling similar algebraic simplifications in the future.

Final Simplified Expression

After applying the distributive property and combining like terms, the final simplified expression for 6(1+8x) is 6 + 48x. This expression is in its simplest form because there are no further operations that can be performed to reduce it. The constant term, 6, and the variable term, 48x, cannot be combined as they are not like terms. A simplified expression is one where all possible operations have been carried out, and there are no remaining parentheses or like terms to combine. The process of simplifying expressions is a fundamental aspect of algebra, and it is essential for solving equations, inequalities, and other mathematical problems. The simplified form not only makes the expression easier to understand but also facilitates further calculations and manipulations. In this case, the transition from the initial expression 6(1+8x) to the simplified form 6 + 48x demonstrates the power of the distributive property in streamlining algebraic expressions. This final form is both concise and clear, providing a solid foundation for any subsequent mathematical operations or analyses that may be required.

Why Simplification Matters

Simplifying expressions is a fundamental skill in mathematics, serving as a cornerstone for more advanced topics. When we simplify 6(1+8x) to 6 + 48x, we're not just making the expression shorter; we're making it easier to work with. Simplified expressions are easier to understand, evaluate, and manipulate in subsequent calculations. This is particularly important when solving equations, graphing functions, or tackling complex mathematical problems. Consider solving an equation where 6(1+8x) is part of a larger equation; using the simplified form 6 + 48x will significantly reduce the complexity and the chances of error. Furthermore, simplification reveals the underlying structure of an expression, making it clear how the different components interact. In this case, the simplified form shows the constant term (6) and the variable term (48x) distinctly, which can be crucial for interpreting the expression's meaning in a real-world context. The process of simplification also reinforces algebraic principles, such as the distributive property and combining like terms, which are essential for mathematical proficiency. Mastering these skills enables one to approach more challenging problems with confidence and precision. In essence, simplification is not just a cosmetic change; it's a critical step in mathematical problem-solving that enhances clarity, efficiency, and accuracy.

Common Mistakes to Avoid

When simplifying expressions like 6(1+8x), several common mistakes can occur. One frequent error is only multiplying the constant outside the parentheses by the first term inside, resulting in 6 + 8x instead of 6 + 48x. This mistake overlooks the distributive property's requirement to multiply by every term within the parentheses. Another common mistake is incorrectly applying the order of operations, often by adding 1 and 8x before multiplying by 6. Remember, multiplication should be performed before addition in this context. Sign errors are also prevalent, especially when dealing with negative numbers or subtractions within the parentheses. For example, if the expression were 6(1-8x), incorrectly distributing the 6 could lead to 6 - 8x instead of the correct 6 - 48x. Another mistake is attempting to combine terms that are not like terms. In the simplified expression 6 + 48x, the terms 6 and 48x cannot be combined further because one is a constant and the other is a variable term. Avoiding these mistakes requires a careful and methodical approach. Double-checking each step, particularly the distribution and combination of terms, can significantly reduce the likelihood of errors. Understanding the underlying principles, such as the distributive property and the order of operations, is crucial for accurate simplification. By being aware of these common pitfalls, one can develop strategies to prevent them and ensure the correct simplification of algebraic expressions.

Practice Problems

After distributing, combine any like terms if possible. These practice problems are designed to reinforce the step-by-step approach to simplification, ensuring that you can confidently tackle similar algebraic expressions. Working through these examples will not only improve your accuracy but also deepen your understanding of the underlying mathematical principles.
