Which of the following is a quadratic equation? For those that are, identify the value of a, b and c.
1. x² - 6x + 2 = 0
2. 3x + 5 = 0 7. (x + 2)(x - 3) = 5
3. 2x² + 7x = 15
4. (x + 1)² = 2(x - 3)
5. x² + 2x + 1 = 5x + 6
6. (x - 1) (x + 2) = x(x + 5)
7. (x + 2)(x - 3) = 5
8. x(x² + 3x - 10) = 0
9. (x - 1)² + 3 = 2x + 1
10. (x + 2)³ = x(x² - 10x + 25) ​
