![]() ![]() Hit the calculate button to get the roots. To solve an equation using the online calculator, simply enter the math problem in the text area provided. A quadratic is a second degree polynomial of the form: ax2 + bx + c 0 where a 0. When Y is isolated already and the equation is in vertex form, it is easier to pick values of X and calculate Y especially when you have a 2nd degree (quadratic) equation or higher degree. This quadratic equation root calculator lets you find the roots or zeroes of a quadratic equation. On Wolfram|Alpha Quadratic Equation Cite this as:įrom MathWorld-A Wolfram Web Resource. So, you graph the vertex and then find points to the left and right of the vertex. "The Quadratic Function and Its Reciprocal." Ch. 16 in AnĪtlas of Functions. Cambridge, England:Ĭambridge University Press, pp. 178-180, 1992. Recipes in FORTRAN: The Art of Scientific Computing, 2nd ed. Step 2 Move the number term to the right side of the equation: P 2 460P -42000. "Quadratic and Cubic Equations." §5.6 in Numerical ![]() Oxford,Įngland: Oxford University Press, pp. 91-92, 1996.

Handbook of Mathematical Functions with Formulas, Graphs, and Mathematical Tables, 9th printing. Viète was among the first to replace geometric methods of solution with analytic ones, although he apparently did not grasp the idea of a general quadratic equation (Smith 1953, pp. 449-450).Īn alternate form of the quadratic equation is given by dividing (◇) through by : Here we will learn about the quadratic equation and how to solve quadratic equations using four methods: factorisation, using the quadratic equation formula, completing the square and using a graph. ![]() The Persian mathematiciansĪl-Khwārizmī (ca. Symbolab: equation search and math solver - solves algebra, trigonometry and calculus problems step by step. Fractions Simplify Antiderivatives Polynomial Equation Log Equation Partial Derivative Implicit Derivative Tangent Complex Numbers. 1025) gave the positive root of the quadratic formula, as statedīy Bhāskara (ca. Calculators and convertors for STEM, finance, fitness, construction, cooking, and more. 850) had substantially the modern rule for the positive root of a quadratic. Of the quadratic equations with both solutions (Smith 1951, p. 159 Smithġ953, p. 444), while Brahmagupta (ca. (475 or 476-550) gave a rule for the sum of a geometric series that shows knowledge The method of solution (Smith 1953, p. 444). Solutions of the equation, but even should this be the case, there is no record of It is possible that certain altar constructions dating from ca. 210-290) solved the quadratic equation, but giving only one root, even whenīoth roots were positive (Smith 1951, p. 134).Ī number of Indian mathematicians gave rules equivalent to the quadratic formula. In his work Arithmetica, the Greek mathematician Diophantus The Greeks were able to solve the quadratic equation by geometric methods, and Euclid's (ca. ![]()
