**Why understanding quadratic equations?**

- To compute all kind of trajectories (ball, angry bird, jump from a cliff, planets…).
- To compute all kind of optimizations such as maximizing profits on market. - To calculate the power going through electrical circuit.
- Designing telescopes, lenses, curved mirror, camera.
- The golden ratio is found as the positive solution of the quadratic equation x² - x - 1 = 0. (e.g. Leonardo da Vinci’s illustrations on the Divine Proportion, the famous golden spiral, Fibonacci sequence…)
- The Taxman, a quite unpleasant invention we still endure today (ref. Babylonians).
