The quadratic formula stands as a cornerstone in algebra, a powerful tool that enables us to solve quadratic equations of the form $ax^2 + bx + c = 0$. This formula, derived from the method of completing the square, provides a direct pathway to finding the roots, or solutions, of any quadratic equation, regardless of its factorability. When we encounter a result like $\frac{2 \pm \sqrt{36}}{6}$, it signals that the quadratic formula has been applied, and our task is to decipher this expression to reveal the actual solutions. In this article, we will meticulously dissect this result, simplify it, and identify the correct solution set from the given options. This involves understanding the structure of the quadratic formula itself, the significance of the $\pm$ symbol, and the arithmetic operations required to arrive at the final answers. Beyond the immediate problem, we will also explore the broader implications of the quadratic formula in solving real-world problems and its connections to other mathematical concepts.

Mastering the quadratic formula is therefore essential for anyone pursuing studies in these fields.

Dissecting the Quadratic Formula Result: A Step-by-Step Approach

The expression $\frac{2 \pm \sqrt{36}}{6}$ encapsulates two potential solutions, thanks to the $\pm$ symbol. This symbol is a shorthand notation that represents both addition and subtraction, indicating that we need to consider two separate cases to find the individual solutions. Let's break down the expression step by step to unveil these solutions.

First, we focus on simplifying the square root. The square root of 36, denoted as $\sqrt{36}$, is simply 6, since 6 multiplied by itself equals 36. Replacing $\sqrt{36}$ with 6, our expression transforms into $\frac{2 \pm 6}{6}$. This seemingly small simplification is a crucial step, as it allows us to move from a complex expression involving a square root to a more manageable arithmetic calculation. With the square root resolved, we can now clearly see the two paths diverging: one involving addition and the other subtraction. This is where the $\pm$ symbol truly comes to life, guiding us to explore both possibilities to uncover the complete solution set.

Next, we address the two cases separately. In the first case, we consider the addition: $\frac{2 + 6}{6}$. This simplifies to $\frac{8}{6}$, which can be further reduced to $\frac{4}{3}$ by dividing both the numerator and denominator by their greatest common divisor, 2. This fraction, $\frac{4}{3}$, represents one of the solutions to the quadratic equation. It's a rational number, expressed in its simplest form, and it provides a specific value that satisfies the original equation. In the second case, we consider the subtraction: $\frac{2 - 6}{6}$. This simplifies to $\frac{-4}{6}$, which can be reduced to $\frac{-2}{3}$ by dividing both the numerator and denominator by 2. This fraction, $\frac{-2}{3}$, represents the second solution to the quadratic equation. It's also a rational number, expressed in its simplest form, and it provides another specific value that satisfies the original equation.

By meticulously simplifying the expression and addressing both the addition and subtraction cases, we have successfully identified the two solutions arising from the quadratic formula result. These solutions, $\frac{4}{3}$ and $\frac{-2}{3}$, form the solution set for the quadratic equation, providing a complete answer to the problem. This step-by-step approach highlights the importance of careful simplification and attention to detail in mathematical problem-solving.

Identifying the Correct Solution Set: Matching the Results

Having meticulously simplified the expression $\frac{2 \pm \sqrt{36}}{6}$, we have arrived at two distinct solutions: $\frac{4}{3}$ and $\frac{-2}{3}$. Our next crucial step is to compare these solutions with the provided options to pinpoint the correct solution set. This involves carefully examining each option and determining whether it accurately reflects the solutions we have calculated. The options presented are:

A. $\left(-\frac{2}{3}, \frac{4}{3}\right)$ B. $(2)$ C. $(1, 3)$

By direct comparison, we can immediately see that option A, $\left(-\frac{2}{3}, \frac{4}{3}\right)$, perfectly aligns with our calculated solutions. This option explicitly lists both $\frac{-2}{3}$ and $\frac{4}{3}$ as elements of the solution set, precisely matching the results we obtained through simplification. This clear correspondence confirms that option A is the correct answer. The other options, B and C, do not contain both of the solutions we found. Option B, $(2)$, presents only a single solution, which is not among our calculated solutions. Option C, $(1, 3)$, offers two solutions that are entirely different from $\frac{4}{3}$ and $\frac{-2}{3}$. Therefore, these options can be confidently ruled out as incorrect.

The process of matching our calculated solutions with the provided options underscores the importance of accuracy and attention to detail in mathematical problem-solving. It's not enough to simply arrive at the solutions; we must also ensure that we correctly identify the option that accurately represents those solutions. This step reinforces our understanding of the problem and solidifies our confidence in the final answer. By systematically comparing our results with the options, we demonstrate a comprehensive grasp of the solution process, from the initial simplification to the final selection of the correct solution set. This meticulous approach is essential for success in mathematics and other problem-solving disciplines.

The quadratic formula can help determine break-even points, where revenue equals cost, and to optimize production levels for maximum profit. This is essential for businesses to operate efficiently and achieve their financial goals. Understanding these applications highlights the practical relevance of the quadratic formula in the business world.

Moreover, in computer science, quadratic equations find applications in algorithm design and optimization problems. Many algorithms involve finding the roots of equations, and the quadratic formula provides a direct way to solve quadratic equations. This is particularly useful in areas such as computer graphics, where quadratic equations are used to model curves and surfaces. The efficiency and accuracy of these algorithms often depend on the ability to solve quadratic equations effectively.

The quadratic formula, therefore, is not merely a formula; it's a gateway to understanding and solving a wide range of real-world problems.
