Understanding the Initial Expression
Before we embark on the simplification process, let's first dissect the expression 6(2s + 4s - 4) - 4s. This expression comprises several key components, each playing a crucial role in the overall structure. We have a term enclosed within parentheses, which involves the variable 's' and constants, indicating that we will likely need to apply the distributive property to eliminate these parentheses. The presence of addition and subtraction operations within the parentheses also suggests that we might need to combine like terms. Outside the parentheses, we have a coefficient multiplying the entire parenthetical expression, further emphasizing the need for distribution. Finally, the subtraction of '4s' from the result introduces another term involving the variable 's', which will eventually need to be combined with other 's' terms to achieve the simplest form. At its core, this expression represents a mathematical relationship where the value depends on the variable 's'. Simplifying it not only makes it easier to work with but also reveals the underlying structure more clearly. To fully grasp the expression, it is essential to identify each term and operation, setting the stage for a methodical simplification process. Understanding the initial expression is the cornerstone of the entire simplification exercise, allowing us to anticipate the necessary steps and avoid common pitfalls. This detailed examination ensures that we approach the problem with a clear roadmap, transforming a potentially confusing expression into a solvable equation.
Applying the Distributive Property
The distributive property is a fundamental concept in algebra that allows us to simplify expressions involving parentheses. In our expression, 6(2s + 4s - 4) - 4s, the term '6' is multiplied by the entire expression within the parentheses. The distributive property dictates that we must multiply '6' by each term inside the parentheses individually. This means we'll multiply '6' by '2s', then '6' by '4s', and finally '6' by '-4'. Let's break this down step-by-step. First, 6 multiplied by 2s gives us 12s. Next, 6 multiplied by 4s gives us 24s. Lastly, 6 multiplied by -4 gives us -24. Therefore, applying the distributive property to the first part of the expression, 6(2s + 4s - 4), results in 12s + 24s - 24. It's crucial to pay close attention to the signs of each term during this process. A negative sign can significantly impact the final result. The distributive property essentially expands the expression, removing the parentheses and allowing us to combine like terms in the subsequent steps. Without this step, simplifying the expression would be considerably more challenging. The distributive property is not just a mathematical trick; it reflects the fundamental way multiplication interacts with addition and subtraction. It's a cornerstone of algebraic manipulation and a skill that's essential for solving equations and simplifying expressions. Mastering the distributive property is akin to unlocking a key that opens the door to more complex algebraic concepts. It allows us to transform expressions into forms that are easier to understand and manipulate, laying the groundwork for further simplification.
Combining Like Terms
After applying the distributive property, our expression now looks like this: 12s + 24s - 24 - 4s. The next crucial step in simplifying this expression is to combine like terms. Like terms are those terms that have the same variable raised to the same power. In this case, we have three terms that contain the variable 's': 12s, 24s, and -4s. The constant term, -24, is not a like term with the 's' terms, as it doesn't have the variable 's' associated with it. To combine the like terms, we simply add or subtract their coefficients. The coefficient is the numerical part of the term. So, we add the coefficients of the 's' terms: 12 + 24 - 4. This gives us 36 - 4, which equals 32. Therefore, combining the 's' terms results in 32s. The constant term, -24, remains unchanged as there are no other constant terms to combine it with. Remember, we can only combine terms that have the same variable and the same exponent. For instance, we couldn't combine an 's' term with an 's²' term, as the exponents are different. Combining like terms is a simplification process because it reduces the number of terms in the expression, making it more concise and easier to interpret. It's like gathering similar objects together to make them easier to count. This step is vital in solving equations, as it allows us to isolate the variable and find its value. It's also crucial in various applications of algebra, such as in physics, engineering, and economics, where simplified expressions can lead to clearer insights and more efficient calculations. By combining like terms, we're essentially tidying up the expression, making it more manageable and paving the way for further analysis or computation.
The Simplified Expression
Having applied the distributive property and combined like terms, we arrive at the simplified form of the expression 6(2s + 4s - 4) - 4s. The simplified expression is 32s - 24. This final form is much more concise and easier to understand than the original expression. It clearly shows the relationship between the variable 's' and the expression's value. The term '32s' indicates that for every unit increase in 's', the expression's value increases by 32 units. The constant term '-24' represents the expression's value when 's' is zero. This simplified form makes it much easier to evaluate the expression for different values of 's', graph the corresponding equation, or use it in further calculations. The simplification process has essentially distilled the expression down to its core components, revealing the underlying mathematical relationship in its clearest form. It's like taking a complex machine and understanding its basic functioning parts. The simplified expression not only saves time and effort in calculations but also provides a deeper understanding of the mathematical concept being represented. The ability to simplify expressions is a fundamental skill in algebra and is crucial for solving equations, analyzing functions, and tackling more advanced mathematical concepts. The journey from the initial complex expression to the simplified form of 32s - 24 showcases the power of algebraic manipulation and the importance of mastering these fundamental techniques. This simplified expression is not just an end result; it's a stepping stone to further mathematical exploration and problem-solving.
