Let's embark on this mathematical journey together, unraveling the intricacies of the equation and discovering its exact solutions.
Understanding the Equation Structure
Before diving into the solution process for the equation -8(t^2 + 13)(t^2 - 3) = 0, it's crucial to understand its structure. This equation is a product of three factors: -8, (t^2 + 13), and (t^2 - 3). The equation is set to zero, which is a key characteristic that allows us to use the Zero Product Property. This property states that if the product of several factors is zero, then at least one of the factors must be zero. Applying this to our equation, we can set each factor equal to zero and solve for t. This approach simplifies the problem into smaller, more manageable equations. Understanding this fundamental principle is the first step in efficiently solving the equation and finding the exact solutions. The constant factor -8, while present, does not contribute to the solutions for t since -8 = 0 is not a valid statement. Therefore, our focus will be on the quadratic factors (t^2 + 13) and (t^2 - 3), which hold the key to the solutions. By recognizing this structure, we can strategically apply algebraic techniques to isolate t and determine its exact values. This initial analysis is not just a preliminary step but a cornerstone of our problem-solving approach.
Applying the Zero Product Property
The Zero Product Property is the cornerstone of solving the equation -8(t^2 + 13)(t^2 - 3) = 0. This property dictates that if the product of several factors equals zero, then at least one of these factors must be zero. In our equation, we have three factors: -8, (t^2 + 13), and (t^2 - 3). As we've established, the constant factor -8 cannot be zero, so we focus on the other two factors. We set each of these factors equal to zero, creating two separate equations: t^2 + 13 = 0 and t^2 - 3 = 0. These equations are simpler to solve individually than the original equation. This step is a critical simplification, transforming a complex problem into two more manageable ones. By applying the Zero Product Property, we've effectively broken down the original equation into its essential components, each of which can be solved independently. This approach not only simplifies the algebra but also provides a clear pathway to finding all possible solutions for t. The beauty of this property lies in its ability to transform a seemingly daunting problem into a series of straightforward calculations, making the solution process more accessible and less prone to errors. This foundational step is pivotal in our quest for the exact solutions of the equation.
Solving t^2 + 13 = 0
Now, let's tackle the first of our simplified equations: t^2 + 13 = 0. Our goal is to isolate t and find its values. To begin, we subtract 13 from both sides of the equation, resulting in t^2 = -13. This equation presents an interesting challenge because we are looking for a number that, when squared, gives a negative result. In the realm of real numbers, this is impossible, as the square of any real number is non-negative. However, we can venture into the realm of complex numbers to find solutions. Complex numbers involve the imaginary unit i, where i^2 = -1. To proceed, we take the square root of both sides of the equation t^2 = -13. This gives us t = ±√(-13). We can rewrite √(-13) as √(13 * -1), which is equivalent to √(13) * √(-1). Since √(-1) is defined as i, we have t = ±√(13) * i. Therefore, the solutions for this equation are t = √(13)i and t = -√(13)i. These are complex conjugate pairs, which is a common occurrence when solving quadratic equations with negative discriminants. These solutions, while not real, are crucial components of the complete solution set for the original equation. This process demonstrates how the introduction of complex numbers allows us to find solutions even when dealing with negative square roots, expanding our ability to solve a wider range of equations. The exact solutions we've found here are vital for a comprehensive understanding of the equation's behavior.
Solving t^2 - 3 = 0
Next, we address the second simplified equation: t^2 - 3 = 0. This equation is similar to the previous one but involves a positive constant, making its solutions real numbers. To isolate t, we first add 3 to both sides of the equation, which gives us t^2 = 3. Now, we take the square root of both sides to solve for t. Remember that taking the square root of a number yields both positive and negative solutions, so we have t = ±√3. This means there are two real solutions for this equation: t = √3 and t = -√3. These solutions are expressed in their exact form, as √3 is an irrational number and cannot be simplified further as a rational number. Unlike the previous equation, this one yields real number solutions, highlighting the diverse nature of solutions that can arise from quadratic equations. The simplicity of this equation allows for a straightforward solution process, emphasizing the importance of recognizing and applying basic algebraic principles. These real solutions, along with the complex solutions from the previous equation, form the complete set of solutions for the original equation. This step reinforces the concept that a single equation can have multiple solutions, each with its own characteristics and significance. The exact solutions we've obtained here are crucial for a comprehensive understanding of the equation's behavior.
Combining the Solutions
Having solved both simplified equations, we now combine the solutions to obtain the complete solution set for the original equation, -8(t^2 + 13)(t^2 - 3) = 0. From solving t^2 + 13 = 0, we found two complex solutions: t = √(13)i and t = -√(13)i. These solutions involve the imaginary unit i and represent values of t that are not real numbers. From solving t^2 - 3 = 0, we found two real solutions: t = √3 and t = -√3. These solutions are real numbers, meaning they can be plotted on a number line. The complete solution set, therefore, consists of these four values: √(13)i, -√(13)i, √3, and -√3. These are the exact solutions to the equation, meaning they are expressed in their most precise form, without any approximation. Combining both real and complex solutions gives us a comprehensive understanding of the equation's behavior across the number system. This complete set illustrates how a single equation can have a diverse range of solutions, each with its own properties and significance. The process of combining these solutions emphasizes the importance of solving each part of the equation thoroughly and then bringing the results together for a holistic view. These exact solutions are not just numerical answers; they are key insights into the nature of the equation and its mathematical characteristics.
Expressing Solutions in Exact Form
Throughout the process of solving the equation -8(t^2 + 13)(t^2 - 3) = 0, we have emphasized the importance of expressing solutions in their exact form. This means that we avoid decimal approximations and instead, retain the solutions as radicals (square roots) or complex numbers involving the imaginary unit i. For instance, the solutions t = √3 and t = -√3 are left as they are, rather than being approximated as 1.732 and -1.732, respectively. Similarly, the complex solutions t = √(13)i and t = -√(13)i are maintained in their exact form, preserving the radical and the imaginary unit. Expressing solutions in exact form is crucial for several reasons. First, it maintains the precision of the solutions, avoiding any rounding errors that can accumulate with approximations. Second, it provides a clearer understanding of the mathematical nature of the solutions, revealing their relationship to the original equation and to each other. Third, it is often a requirement in mathematical contexts where exactness is paramount, such as in theoretical calculations or proofs. In our case, the exact solutions reveal the presence of both real and complex roots, each with its own distinct characteristic. By adhering to the principle of exact form, we ensure that our solutions are not only accurate but also mathematically meaningful. This approach reflects a commitment to precision and a deeper engagement with the underlying mathematical concepts. The exact solutions we've obtained serve as a testament to the power of algebraic methods in revealing the true nature of equations.
