Unveiling The Simplified Form Of (5-w)²: A Mathematical Journey

Decoding the Expression: $(5-w)^2$

Let's embark on a mathematical adventure where we simplify and rewrite the expression $(5-w)^2$. This seemingly simple equation holds the key to understanding a fundamental concept in algebra: expanding binomials. To start, let's break down what this expression truly represents. The term $(5-w)^2$ signifies that we are multiplying the binomial $(5-w)$ by itself. In other words, it's equivalent to $(5-w) * (5-w)$. Think of it like this: if you have a number and square it, you're essentially multiplying that number by itself. In this case, our number is the binomial $(5-w)$. Therefore, the expression is a compact notation for the product of $(5-w)$ with itself. This is the cornerstone of our simplification process. We need to meticulously perform the multiplication to unveil the simplified form. The parentheses in the original expression dictate the order of operations, signaling that we first perform the subtraction within the parentheses before squaring the result. However, when we expand the expression, we'll bypass the need for direct subtraction and instead use the distributive property to handle the multiplication. The core idea is to apply the distributive property, sometimes remembered by the acronym FOIL (First, Outer, Inner, Last), which provides a systematic method for multiplying binomials. This helps to ensure we don't miss any terms during our expansion. It's important to understand the components of the expression. We have a constant, 5, and a variable, 'w', being subtracted, all enclosed within parentheses and raised to the power of 2. Removing the parentheses and simplifying will allow us to represent the expression in an equivalent yet expanded form. This expanded form reveals the quadratic nature of the expression, where the variable 'w' will be raised to the power of 2, indicating the presence of a quadratic term. The simplification process will transform this single, squared term into a trinomial, revealing the interplay between the constant and the variable. Our journey aims to transform $(5-w)^2$ from its compact, squared form to a more detailed and revealing expanded form. The expression $(5-w)^2$ is more than just a mathematical statement; it's a doorway to a deeper understanding of algebraic manipulation and polynomial expansion, so stay focused.

Step-by-Step Simplification: Expanding the Binomial

Now, let's dive into the step-by-step simplification of $(5-w)^2$. The goal is to remove the parentheses and express the equation in a more accessible and simplified format. Our primary tool for achieving this is the distributive property or the FOIL method, which helps us methodically multiply the terms. The FOIL method provides a structured approach, ensuring that all terms are accounted for in the expansion process. We start by multiplying the First terms of each binomial: $5 * 5 = 25$. Next, we multiply the Outer terms: $5 * -w = -5w$. Then, we multiply the Inner terms: $-w * 5 = -5w$. Finally, we multiply the Last terms: $-w * -w = w^2$. Now, let's put it all together. We have $25 - 5w - 5w + w^2$. Observe that there are two like terms in the middle: $-5w$ and $-5w$. These can be combined by adding their coefficients. Combining these like terms, we get $-5w - 5w = -10w$. The complete expanded expression becomes $25 - 10w + w^2$. This is the simplified form of $(5-w)^2$. It's a quadratic expression, meaning that the highest power of the variable 'w' is 2. The original expression, when expanded, yields a trinomial consisting of a constant term, a linear term (involving 'w'), and a quadratic term (involving 'w²'). The simplification process reveals the inherent structure of the expression. The initial form hides the individual components, but the expanded form showcases each term's contribution. It's like taking a complex machine apart to see how all the gears and levers function together. Remember, the FOIL method is simply a mnemonic device. It helps to organize the multiplication of each term in one binomial by each term in the other. It is an effective technique, and mastering it helps greatly when solving more complex equations. By breaking down the expression step-by-step, we've demonstrated how to rewrite $(5-w)^2$ without parentheses and in a simplified form. The expanded expression is equivalent to the original but written in a more detailed, comprehensive manner.

The Simplified Result: Unveiling the Final Form

After diligently applying the steps of the distributive property and combining like terms, we have arrived at our simplified result. The simplified form of $(5-w)^2$ is $w^2 - 10w + 25$. This form offers a clearer view of the expression's components. Unlike the original squared binomial, the expanded form shows each term and its respective contribution. The original expression represents a compact algebraic formula, while its expanded counterpart demonstrates the individual operations required to arrive at a solution. The simplified form of $w^2 - 10w + 25$ is the final form, a quadratic expression where we can readily identify the different terms: the quadratic term ($w^2$), the linear term ($-10w$), and the constant term (25). In this form, we can clearly see the quadratic nature of the original expression. The variable 'w' is raised to the power of 2, indicating that the graph of this expression would be a parabola. The constant term influences the vertical position of the parabola, and the coefficient of the linear term affects the parabola's axis of symmetry. The simplification is a foundational skill in algebra. It helps us to solve equations, understand functions, and manipulate algebraic expressions more effectively. Being able to simplify an expression like $(5-w)^2$ demonstrates a solid understanding of fundamental algebraic principles. The final, simplified form, $w^2 - 10w + 25$, is the result of the expansion and simplification process, making it useful in a wide array of mathematical contexts. This simplified form is not only mathematically equivalent to the original expression but also unlocks new perspectives in analyzing and solving related problems. It becomes easier to see how this expression might interact with other equations or how it could be used within more complex calculations.
