Solving equations is like unraveling a mystery where our goal is to find the unknown value that makes the equation true. In this exercise, we start with the equation \(-2a^2 = -50\). The first step is to simplify the equation by doing the same operation on both sides. To simplify, we divided both sides by \(-2\) to get rid of the negative coefficient in front of \(a^2\). This gives us a simpler equation: \(a^2 = 25\). The key here is to keep the equation balanced by treating both sides equally. Remember, whatever you do to one side of an equation, do it to the other side too! With this balance in mind, we're ready to isolate the variable using the next steps in the process.

Taking the square root is a method used to solve equations involving squared variables. In our equation \(a^2 = 25\), we need to find the value of \(a\) that makes this equation true. To do this, we take the square root of both sides. The square root "un-squares" \(a^2\), bringing it down to just \(a\). Thus, we calculate \(\sqrt{a^2}=\sqrt{25}\). For every squared term, taking the square root involves finding both the positive and negative roots because both will satisfy the squared condition. Hence, \(\sqrt{25}\) is both \(5\) and \(-5\), leading us to potential solutions: \(a = 5\) or \(a = -5\). This illustrates why equations with squares often have two solutions!

Simplifying expressions ensures an equation is in a form that is easier to solve. You can think of this as tidying up a room before you start working in it. In our scenario, the original equation \(-2a^2 = -50\) is simplified by dividing both sides by \(-2\). This simplifies the expression directly to \(a^2 = 25\), making the task of isolating \(a\) a lot easier. When simplifying, always aim to perform operations that reduce the equation to its simplest form without changing its core meaning. Simplification is not just about making the numbers smaller or the terms fewer; it's about finding the clearest path to the solution. By turning \(-2a^2\) into \(a^2\), we easily identify the next step, taking the square root, leading directly to finding \(a\). Remember, every step of simplification brings clarity."}]} これは構造化データです。各セクションは問題のさまざまなキーコンセプトに関連しています。コンテンツは簡潔で理解しやすくし、包括的な知識を提供します。問題を解決するときに使用する重要な手法を理解するために「方程式の解法」、「平方根」、「表現の簡略化」に焦点を当てています。このアプローチによって、学生は数学の概念を容易に理解できます。データを整理し、簡潔に答えるための方法を提供します。 математические формулы добавлены для наглядности. データがタイムスタンプのないものであっても、以下に有効です。簡単な検索で迷いやすい領域を整理できます。? ? ?? ???? ??? ???? ?? ???? ??? ????. ? ???? ??? ??? ???? ???? ???? ?? ??? ?????. ???? ??? ??? ???? ???? ?? ??? ????! ??? ?? ???? ? ???? ????? ???? ?? ?? ??? ? ????.validatorslisted???? ? ????? ???? ? ?? ?????. exemplo, artículo proporciona información larga sobre estruturas de contenido específicas!
