Answer

Here are the solutions for each equation: 1. \( x^{2} = 4 \) → \( x = 2 \) and \( x = -2 \) 2. \( x^{2} = -4 \) → \( x = 2i \) and \( x = -2i \) 3. \( x^{2} + 2 = 0 \) → \( x = i\sqrt{2} \) and \( x = -i\sqrt{2} \) 4. \( x^{2} - 2 = 0 \) → \( x = \sqrt{2} \) and \( x = -\sqrt{2} \) 5. \( x^{2} = -32 \) → \( x = 4\sqrt{2}\,i \) and \( x = -4\sqrt{2}\,i \) 6. \( x^{2} = 32 \) → \( x = 4\sqrt{2} \) and \( x = -4\sqrt{2} \) 7. \( x - 2 = 0 \) → \( x = 2 \) 8. \( x + 2 = 0 \) → \( x = -2 \)

Solution

Certainly! Below is the matching of each equation with its corresponding solution(s): --- **1. \( x^{2} = 4 \)** - **Solutions:** \( x = 2 \) and \( x = -2 \) --- **2. \( x^{2} = -4 \)** - **Solutions:** \( x = 2i \) and \( x = -2i \) *(No real solutions; solutions are imaginary numbers.)* --- **3. \( x^{2} + 2 = 0 \)** - **Solutions:** \( x = i\sqrt{2} \) and \( x = -i\sqrt{2} \) *(No real solutions; solutions are imaginary numbers.)* --- **4. \( x^{2} - 2 = 0 \)** - **Solutions:** \( x = \sqrt{2} \) and \( x = -\sqrt{2} \) --- **5. \( x^{2} = -32 \)** - **Solutions:** \( x = 4\sqrt{2}\,i \) and \( x = -4\sqrt{2}\,i \) *(No real solutions; solutions are imaginary numbers.)* --- **6. \( x^{2} = 32 \)** - **Solutions:** \( x = 4\sqrt{2} \) and \( x = -4\sqrt{2} \) --- **7. \( x - 2 = 0 \)** - **Solution:** \( x = 2 \) --- **8. \( x + 2 = 0 \)** - **Solution:** \( x = -2 \) --- **Summary Table:** | Equation | Solutions | |------------------|------------------------------------| | \( x^{2} = 4 \) | \( x = 2, -2 \) | | \( x^{2} = -4 \) | \( x = 2i, -2i \) | | \( x^{2} + 2 = 0 \) | \( x = i\sqrt{2}, -i\sqrt{2} \) | | \( x^{2} - 2 = 0 \) | \( x = \sqrt{2}, -\sqrt{2} \) | | \( x^{2} = -32 \) | \( x = 4\sqrt{2}\,i, -4\sqrt{2}\,i \) | | \( x^{2} = 32 \) | \( x = 4\sqrt{2}, -4\sqrt{2} \) | | \( x - 2 = 0 \) | \( x = 2 \) | | \( x + 2 = 0 \) | \( x = -2 \) | --- **Notes:** - **Real Solutions:** Equations 1, 4, 6, 7, and 8 have real solutions. - **Imaginary Solutions:** Equations 2, 3, and 5 have no real solutions and instead have imaginary (complex) solutions.
