"In elementary algebra, a quadratic equation (from the Latin quadratus for "square") is any equation having the form

ax^2+bx+c=0

where x represents an unknown, and a, b, and c are constants with a not equal to 0. If a = 0, then the equation is linear, not quadratic. The constants a, b, and c are called, respectively, the quadratic coefficient, the linear coefficient and the constant or free term.

Because the quadratic equation involves only one unknown, it is called "univariate". The quadratic equation only contains powers of x that are non-negative integers, and therefore it is a polynomial equation, and in particular it is a second degree polynomial equation since the greatest power is two.

Quadratic equations can be solved by a process known in American English as factoring and in other varieties of English as factorising, by completing the square, by using the quadratic formula, or by graphing." [Quadratic equation. Wikipedia]

The flowchart example "Solving quadratic equation algorithm" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Mathematics solution from the Science and Education area of ConceptDraw Solution Park.

## Basic Diagramming

Mathematical Drawing Software - Draw mathematical illustration diagrams easily from examples and templates!## Mathematics

Mathematics solution extends ConceptDraw DIAGRAM software with templates, samples and libraries of vector stencils for drawing the mathematical illustrations, diagrams and charts.

## Flowcharting Software

Creating a flowchart that is known to be a type of diagram that represents some algorithm, some process or some workflow may be a challenge for those who never had any experience in doing it before. Having such useful tool as the ConceptDraw DIAGRAM diagramming and drawing software it is possible, but once there is an opportunity to use a relatively new Flowcharts solution from the ConceptDraw STORE application, then it would worth to take it.## Software Diagrams

Design and document development of projects using a wide range of pre-drawn shapes and smart connectors. Develop visualization solutions with the help of the built-in scripting language.ConceptDraw DIAGRAM is a perfect tool for Designing and planning tasks; Developing Visualization Solutions; Project Planning (Gantt Charts, Timelines, Project Schedules).
