Students often wonder if a quadratic equation can have more than one solution? Are there any equations that donвЂ™t have any real solution? Yes, itвЂ™s possible with the root of quadratic equation concept. Using the quadratic equation formula, x = (в€’2 В± в€љ0)/2 = в€’2/2Дownload the Quadratic Equation Cheat Sheet online HereвЂ™s an example that will give you an understanding on what it takes while solving quadratic equations. The quantity in the square root is called the discriminant or D. Just plug in the values of a, b and c, and do the calculations. If ax 2 + bx + c = 0 is a quadratic equation, then the value of x is given by the following formula:

Below-mentioned is the general quadratic equation formula. Quadratic Equation Formula/ Formulas for Solving Quadratic EquationsДЇormulas for solving quadratic equations provide students with requisite knowledge to deal with complex numericals easily. In 12th century, Spain, a Jewish mathematician Abraham bar Hiyya Ha-Nasi authored the first European book that included a complete solution to the general quadratic equation and finally in 1637, RenГ© Descartes, published La GГ©omГ©trie that contained all the quadratic equation formula that we know today.

Over time, various historians kept innovating new ways of finding new formulas for solving quadratic equations. ItвЂ™s a known fact that mathematicians from Babylonia, Egypt, Greece, China, and India used geometric methods to solve quadratic equations. When we take a peek into the history, practical applications of quadratic equations are dated way back, as early as 2050 BC. Therefore, they are also called вЂњEquations of degree 2вЂќ. The word quadratic in the term Quadratic equations is derived from quadratus, a Latin word for вЂsquare.вЂ™ Hence, we define quadratic equations as equations where the variable is of the second degree.
