Respuesta:
1. x² + x - 2x - 2 = x² - x - 2
2. m² - 2m + 3m - 6 = m² + m - 6
3. r² - 4r + 7r - 28 = r² + 3r - 28
4. k² - 2k - 10k + 20 = k² - 12k + 20
5. b² - 5b - 6b + 30 = b² - 11b + 30
6. 4a² + 8a - 12a - 24 = 4a² - 4a - 24
7. z² - 4z - 3z + 12 = z² - 7z + 12
8. x² + 6x + 4x + 24 = x² + 10x + 24
9. 16n² - 8n - 20n + 10 = 16n² - 28n + 10
10. x⁴ + 5x² - 10x² - 50 = x⁴ - 5x² - 50
