Squaring a number means multiplying it by itself (e.g., 12 × 12 = 144). This equation asks: Which number, when multiplied by itself, equals 144?", "---", "### Step-by-Step Solution: Solving s² = 144", "To find the value(s) of s, follow these simple algebraic steps:", "1. Start with the equation:
\n [
\n s^2 = 144
\n ]", "2. Take the square root of both sides:
\n To isolate s, apply the square root operation to both sides. Remember, taking the square root gives both a positive and negative solution because a negative number squared is also positive:
\n [
\n s = \pm \sqrt{144}
\n ]", "3. Compute the square root:
\n The square root of 144 is 12, since 12 × 12 = 144.
\n [
\n s = \pm 12
\n ]", "4. Write the final solutions:
\n Therefore, s can be either 12 or –12:
\n [
\n s = 12 \quad \ ext{or} \quad s = -12
\n ]", "---", "### Why Is s = 12 One of the Solutions?", "Focusing on s = 12, it directly satisfies the original equation:", "[
\n12^2 = 12 \ imes 12 = 144
\n]", "This confirms that 12 is a valid solution. In algebra, solving equations like s² = k always yields two solutions—positive and negative—unless k is negative (where solutions remain imaginary). So while s = -12 is equally valid, s = 12 is one key solution every learner should recognize.", "---", "### Real-World Applications of s² = 144 and Its Solutions", "Though simple, equations involving squares appear frequently in real life and STEM fields:", "- Physics: Calculating distances, energy expressions often involve squared variables. For example, the kinetic energy formula ( KE = \frac{1}{2}mv^2 ) relies on squaring velocity.
\n- Engineering and Design: When sizing components or determining dimensions, squaring dimensions helps model areas, volumes, or stress factors.
\n- Computer Graphics: Squaring differences underlie distance formulas, critical for rendering and animations.", "Understanding s² = 144 prepares you to tackle these real-world problems by building confidence in quadratic solving techniques.", "---", "### Common Mistakes to Avoid", "- Forgetting both the positive and negative roots. Remember: ( \sqrt{x^2} = |x| ), so solutions must reflect both signs.
\n- Miscalculating square roots: always check that 12 × 12 indeed equals 144.
\n- Assuming s = 144 is a solution—verify by substitution: ( 144^2 <br/>\neq 144 ).", "---", "### Final Thoughts", "The equation s² = 144 and its solution s = 12 may seem elementary, but it forms a crucial building block in algebra. Recognizing how squaring works, determining both roots, and applying these concepts to practical contexts enhances both mathematical fluency and problem-solving skills.", "So, whether you are studying for an exam, tackling homework, or simply curious about equations, remember:
