What is the improved quadratic formula in solving quadratic equations?
The improved quadratic formula (Google, Yahoo, Bing Search)
The improved quadratic formulas;
D = d^2 = b^2 - 4ac (1)
In this formula:
- 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.
