One of the biggest traumas for school children in modern times is the second-degree equation, where they make them memorize formulas. This memorize make students hate math. Notice what it is like to teach in a modern school. The equation of 2° degree is given by: $$ax^2 + bx + c = 0$$ in which $$\Delta = b^2 - 4ac$$From this, we obtain that the roots of Bhãskara’s equation: $$x = \frac{-b\pm \sqrt{\Delta}}{2a}$$ Bhãskara’s work The work of Bhãskara(around 1070 AD), which cites the writings of Śridhara (around 1030 AD), is what went down in history as the author of solving the equations of 2° degree. The first to work on this topic was Al-Khowarizm, in approximately 1000 AD, who is cited by Śridhara.
