## Basic Concept

Quadratic equation takes the form of ax2 +bx +c = 0, in which the left-hand side can be factored over the integers. For example:

2x2 -5x +2 = 0

(2x-1)(x-2) = 0

x = 1/2 or x = 2

In this case, you can solve the equation by inspection. Sometime it is difficult to do so, this module provides solutions for any solvable quadratic equations.

The roots, if solvable, are calculated using following:

x1,2 = [-b± sqrt(b2-4ac)]/2a

The results are displayed in the form of decimal rather than fraction.

## Feature Overview

This module allows solution of typical quadratic equation, giving two roots as answers.

This solves quadratic equation by providing the coefficients of a, b, and c.

## User Instructions

Enter values of a, b, and c and click Calculate button to get result. Click Reset to clear all numbers and start over. Notice the answers are displayed in decimals, round them off if needed.

Note: If the equation is not solvable, the error message will appear to indicate that.
