Deciphering the Equation (x-2)(4+x)=0

Alright, let’s break down this equation like seasoned math detectives. The beauty of the equation (x-2)(4+x)=0 lies in its factored form. This is a major clue! It's practically screaming at us to use a powerful tool called the zero-product property. Now, what's the zero-product property, you ask? It's a fundamental principle in algebra that states if the product of two or more factors is zero, then at least one of the factors must be zero. Think of it like this: if you're multiplying numbers and the answer is zero, then one of those numbers has to be zero. This simple yet profound concept is the key to unlocking our solutions. In our equation, we have two factors: (x-2) and (4+x). According to the zero-product property, either (x-2) must equal zero, or (4+x) must equal zero, or both! This transforms our single equation into two simpler equations that we can solve individually. Isn't that neat? By understanding and applying the zero-product property, we've taken a significant step towards finding the integer solutions. We are essentially dividing the problem into manageable chunks, making the entire process less daunting and more approachable. Now, let's move on to solving these individual equations and uncovering the values of 'x' that satisfy the original equation.

Cracking the Code: Finding Integer Solutions

Okay, guys, let's get our hands dirty and solve those simpler equations we derived. First up, we have (x-2) = 0. This is a straightforward linear equation, and to isolate 'x', we simply add 2 to both sides of the equation. Voila! We get x = 2. Now, let's tackle the second equation: (4+x) = 0. Again, we want to isolate 'x', so we subtract 4 from both sides. And there it is: x = -4. So, we've found two potential solutions: x = 2 and x = -4. But before we jump for joy, we need to make sure these solutions are indeed integers. Remember, the question specifically asks for integer solutions. Integers are whole numbers (no fractions or decimals!) and can be positive, negative, or zero. Thankfully, both 2 and -4 fit this description perfectly. They are whole numbers, one positive and one negative. This confirms that they are valid solutions to our problem. We can even double-check our work by plugging these values back into the original equation to see if they make the equation true. If we substitute x = 2 into (x-2)(4+x) = 0, we get (2-2)(4+2) = 0 * 6 = 0, which is true. Similarly, if we substitute x = -4, we get (-4-2)(4-4) = -6 * 0 = 0, which is also true. This verification step is crucial in ensuring the accuracy of our solutions and building confidence in our problem-solving abilities. We are not just finding answers; we are confirming their validity through rigorous mathematical checks.

The Grand Finale: Solutions Unveiled

Drumroll, please! We've reached the climax of our mathematical quest. We've meticulously dissected the equation (x-2)(4+x)=0, applied the zero-product property like pros, and unearthed the integer solutions. And the winners are… x = 2 and x = -4! These are the two integers that make the equation sing. But wait, there's more! It's not just about finding the solutions; it's about understanding what they represent. In the context of the equation, these values of 'x' are the points where the expression (x-2)(4+x) equals zero. If we were to graph this expression, these solutions would be the x-intercepts, the points where the graph crosses the x-axis. This connection between algebraic solutions and graphical representations is a powerful concept in mathematics, providing a visual understanding of the solutions we've found. Moreover, the fact that we have two solutions is related to the degree of the polynomial formed when we expand the original equation. Expanding (x-2)(4+x) gives us x² + 2x - 8, which is a quadratic polynomial (degree 2). In general, a polynomial equation of degree 'n' can have up to 'n' solutions. This is a fundamental theorem in algebra, and our equation serves as a perfect illustration of this principle. So, not only have we found the integer solutions, but we've also connected them to broader mathematical concepts, enriching our understanding and appreciation of algebra.

Wrapping Up: The Power of Integer Solutions

Alright, mathletes, we've reached the end of our integer solution expedition! We've not only conquered the equation (x-2)(4+x)=0 but also gained a deeper understanding of the zero-product property, integer solutions, and their significance in mathematics.
