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. \( x + 2 = 0 \) → \( x = -2 \)
