Answer:
1. 2x² + 5x - 7 = 0
Solution: a = 2, b = 5, c = -7
Sum of the roots: -5/2
Product of the roots: -7/2
2. 2x² = 5x - 2
Solution: 2x² - 5x + 2 = 0
Sum of the roots: 5/2
Product of the roots: 1
3. (x + 3)² = 14
Solution: (x + 3)² - 14 = 0
x² + 6x + 9 - 14 = 0
x² + 6x - 5 = 0
Sum of the roots: -6
Product of the roots: -4√14-3
