Use the values of a, b, and c of the given quadratic equations below
then determine the sum and product of its roots.
1. x² - 2x - 3 = 0
2. x² + 4x - 21 = 0
3. x² – 3x + 12 = 0
4. 3x² - 15x - 2 = 0
5. 2x² - 3x = 0
then determine the sum and product of its roots.
1. x² - 2x - 3 = 0
2. x² + 4x - 21 = 0
3. x² – 3x + 12 = 0
4. 3x² - 15x - 2 = 0
5. 2x² - 3x = 0
