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

Making Diagrams Has Never Been Easier

The innovative ConceptDraw PRO is a powerful drawing tool that changes the way diagrams are produced. While making diagrams has never been easier. This is more than enough versatility to draw any type of diagram with any degree of complexity.
The vector stencils library "AWS Database" contains 30 Amazon Web Services database icons: Amazon DynamoDB symbols, Amazon Relational Database Service symbols, Amazon ElasticCache symbols, Amazon SimpleDB symbols, Amazon Redshift symbols.
Use it to draw AWS architecture diagrams of your cloud service.
