Quadratic Equation -- from Wolfram MathWorldA simple and easy to use application to determine the roots of a quadratic equation ax²+bx+c=0. Optionally, you can draw the graphic of the function yA quadratic equation is a second-order polynomial equation in a single variable x ax^2+bx+c=0, (1) with a!=0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has two solutions. These solutions may be...
