But sometimes, the quadratic equations might not come in standard form, and we might have to expand it. If a is positive, the graph opens upward, and if a is negative. Here x is the unknown value, and a, b and c are variables. The quadratic function f(x) a(x - h)2 + k, a not equal to zero, is said to be in standard form. In other words, as these developments were happening to solve quadratic equations, many other developments occurred in mathematics. The standard form of quadratic equation is the equation in form of ax2 + bx + c 0. Hackworth and Howland let us know that until Hindu mathematics, mathematics developed in India, existed, numbers did not appear the way we know them, with a base 10 system. In the year 700 AD, Brahmagupta, a mathematician from India, developed a general solution for the quadratic equation, but it was not until the year 1100 AD that the solution we know today was developed by another mathematician from India named Bhaskara, as stated by Mathnasium. According to Mathnasium, not only the Babylonians but also the Chinese were solving quadratic equations by completing the square using these tools. Imagine solving quadratic equations with an abacus instead of pulling out your calculator. The graph comes readily usable and you just have to plot the data over it for the. They can use the template as the full-fledged graph of a quadratic equation and enhance their learnings. All our templates are available for printing purposes to serve the requirements of users. You can learn more about standard form and other forms of quadratic equations in our review article about the forms of quadratics. You can use this template to draw the quadratic equation graph. The coefficient in front of x^2 is a, the coefficient in front of x is b, and the coefficient without a variable is c. The letters a, b, and c come from the standard form of a quadratic equation: Standard Form of Quadratic Equation:
