"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]

How to Draw a Divided Bar Chart

How to Draw a Divided Bar Chart
A divided bar graph is a rectangle divided into smaller rectangles along its length in proportion to the data. Segments in a divided bar represent a set of quantities according to the different proportion of the total amount. A divided bar diagram is created using rectangular bars to depict proportionally the size of each category. The bars in a divided bar graph can be vertical or horizontal. The size of each rectangle displays the part that each category represents. The value of the exact size of the whole must be known because each section of the bar displays a piece of that value. A divided bar diagram is rather similar to a sector diagram in that the bar shows the entire data amount and the bar is divided into several parts to represent the proportional size of each category. ConceptDraw DIAGRAM in conjunction with Divided Bar Diagrams solution provides tools to create stylish divided bar charts for your presentations.
