A is the coefficient of the x^2 term b is the coefficient of the x term c is the constant term they are used in equations to find the roots and in equations to find the minimum / maximum point of a quadratic equation and in equations to find the slope and y-intercept of a straight line, among other uses that I am probably not totally aware of.

The quadratic function y = ax 2 + bx + c is related to the equation ax 2 + bx + c = 0 by letting y equal zero. Notice that we have a minimum point which was indicated by a positive a value (a = 1). In this example we are considering two functions of the same independent variable, price.

The graph of a univariate quadratic function is a parabola whose axis of symmetry is parallel to the y-axis, as shown at right. The process of completing the square makes use of the algebraic identity + + = (+), which represents a well-defined algorithm that can be used to solve any quadratic equation.:. For example, the equation 4y 2 - y + 25 = 0 has solutions given by the horizontal line y = 2.5, but since 2.5 is not an integer number, we will say that the equation.
