state the concept of quadratic equation with the help of an activity
Answers
Step-by-step explanation:
For a parabolic mirror, a reflecting telescope or a satellite dish, the shape is defined by a quadratic equation. Quadratic equations are also needed when studying lenses and curved mirrors. And many questions involving time, distance and speed need quadratic equations.
Examples of Quadratic Equation
6x² + 11x - 35 = 0.
2x² - 4x - 2 = 0.
-4x² - 7x +12 = 0.
20x² -15x - 10 = 0.
x² -x - 3 = 0.
5x² - 2x - 9 = 0.
3x² + 4x + 2 = 0.
-x² +6x + 18 = 0.
There are three basic methods for solving quadratic equations: factoring, using the quadratic formula, and completing the square.

The Work of Al-Khwarizmi
In 825 CE, about 2,500 years after the Babylonian tablets were created, a general method that is similar to today's Quadratic Formula was authored by the Arab mathematician Muhammad bin Musa al-Khwarizmi in a book titled Hisab al-jabr w'al-muqabala.
