Factoring expressions by grouping

Let us study about factoring expressions by grouping,

Introduction to factoring expressions by grouping:

In mathematics, factoring is one of the interesting topics in algebra. Using the grouping method, given polynomial expression can be factored.

Polynomial expressions are the sums of a finite number of monomials. It has more than one term and it has a constant value for the each term, for that variable power of integral is raised to more than two.

Perimeter of a rectangle

Let us study about Perimeter of a Rectangle,
The perimeter of a polygon is out side distance of the polygon. A polygon is 2-dimensional; but, perimeter is 1-dimensional and is measured in linear units.

To find the perimeter of a polygon, take the sum of the length of each side.

The perimeter of a rectangle is ,out side distance of the rectangle.A rectangle has four sides,they are equal in length. The formula for finding the perimeter is Side A + Side B + Side A + Side B. This could also be stated as 2*Side A + 2*Side B or 2*(Side A + Side B) .

Factorising

Factorizing:In algebra equations factorization is one of the important method. Factorization gives the x values of the given algebraic equations.

Factoring the equations gives the desired value of the function. It is very easy and simple. General form of the algebraic equation can be written as, ax2 + bx + c. In factorisation, we find two or more factor values.Usually question are asked based on factors of 64.Quadratic equations are mainly used for factorising process.Hope you like the above example of Factorising.Please leave your comments, if you have any doubts.

What is Mean

Let us understand What is Mean:Mean comes under the topic Statistics. It is classified as one of the measures of dispersion. The other methods that are used to calculate the mean deviation are range, quartile deviations, etc..While calculating range and quartile deviation, we wont consider all the collected data for calculation. But in the measure of dispersion called mean deviation, we consider all the observed values.Let us now look at a more specific explanation of Mean Deviation.The mean deviation of a statistical data is defined as the arithmetic mean of the numerical values of the deviations of items from some average value.Mean deviation is also known as average deviation.The mean deviation is generally denoted by mean symbol M.D.Hope you like the above example of Mean.Please leave your comments, if you have any doubts.

tangent of circle

Let us study about Tangent of Circle,
Tangent is a line which touches a circle at only one point. At the point of contact with the circle, tangent is at right angles to the radius of the circle. From any point outside a circle, the two tangent lines drawn to the circle is of equal length. Tangent to a circle is a straight line and it won't cross the circle-only touching the circle.

Explanation:

Tangent of a circle is the point where the tangent and the circle intersect with each other.

statistics help

Let us understand what is Statistics,
The science that deals with the collection, classification, analysis, and interpretation of numerical facts or data, and that, by use of mathematical theories of probability, imposes order and regularity on aggregates of more or less disparate elements.

Statistics is a discipline which is concerned with:

* designing experiments and other data collection,
* summarizing information to aid understanding,
* drawing conclusions from data, and
* estimating the present or predicting the future.

The two statements at the beginning illustrate some of these points.

In making predictions, Statistics uses the companion subject of Probability, which models chance mathematically and enables calculations of chance in complicated cases.
I hope the above explanation helped you, now let me explain about elementary statistics.

Least common multiple

Least common multiple :

The least common multiple (LCM) is the smallest multiple that is common to two or more numbers.

Example : What is the least common multiple of 2 and 3?

The smallest multiple common to both 2 and 3 is 6.

Example 2 : What is the least common multiple of 2, 3, and 4?
The least common multiple of 2, 3, and 4 is 12.
