** #x = -b/(2a) +- d/(2a)#** (2).

In this formula:

- Quantity

- Quantity

Advantages;

- Simpler and easier to remember than the classical formula.

- Easier for computing, even with a calculator.

- Students understand more about the quadratic function features, such as: vertex, axis of symmetry, x-intercepts.

Classical formula:
