Wintringham Solving Simple Quadratics
- 1. x2 + 4x + 3 = 0 biggest value first, with just a space (e.g. x = 3 x = -9)
- 2. x2 + 5x + 6 = 0 biggest value first, with just a space (e.g. x = 3 x = -9)
- 3. x2 + 16x + 55 = 0 biggest value first, with just a space (e.g. x = 3 x = -9)
- 4. x2 - 10x + 16 = 0 biggest value first, with just a space (e.g. x = 3 x = -9)
- 5. x2 - 11x + 30 = 0 biggest value first, with just a space (e.g. x = 3 x = -9)
- 6. x2 - 9x + 20 = 0 biggest value first, with just a space (e.g. x = 3 x = -9)
- 7. x2 + 3x - 10 = 0 biggest value first, with just a space (e.g. x = 3 x = -9)
- 8. x2 + 6x - 7 = 0 biggest value first, with just a space (e.g. x = 3 x = -9)
- 9. x2 + x - 20 = 0 biggest value first, with just a space (e.g. x = 3 x = -9)
- 10. x2 - x - 6 = 0 biggest value first, with just a space (e.g. x = 3 x = -9)
