Radicals are square roots which are not integers; the square roots of 2 or 3 are examples of radicals. The presenters show simple ways of how to add and subtract such radicals. They explain that by using the method of factoring, the addition or subtraction is made very easy. If the square root of 8, for instance, is in some addition sum, it can be factored into the square root of 4 times the square root 2. Since we know that the square root of 4 is 2 this can be simplified to be 2 times the s...
In this video the instructor shows how to simplify radicals. A radical is nothing but another name for a square root. To find the square root of a simple number the first thing that you need to do is factor it. If you need to compute the square root of a number, you first need to find a number which multiplied by itself gives the original number under the root. For example, to find the square root of 9, you need to find a number which multiplied by itself gives 9. Here the answer is 3. When 3...
This is a great instructional video on how to do inspect a boiler at home. A home inspection must include the boiler and heating system. What you need to look for are corrosion, pressure and blockages. When you buy or sell a house it is better to go in for a boiler inspection. The condition of a boiler depends on many factors. The age factor is also one of the reasons that cause the efficiency of the boiler decrease considerably. If there is some leakage in the pipes it might affect the press...

This video demonstrates the simplest method for multiplying fractions. According to the tutor, one should first identify the highest common factor with which to reduce the two fractions, by themselves, and in relation to each other. The numerators of the two fractions are multiplied and the product is written down as the numerator of the resultant. The same operation is carried out on the denominators of the two fractions, resulting in the denominator of the resultant fraction. The final answ...

In this video the instructor teaches about equivalent fractions. When given a problem to determine if two fractions are equivalent fractions the first thing to do is write them in the lowest terms. A fraction is said to be in the lowest terms if the greatest common divisor of both numerator and denominator is one. So cancel the common factors in the numerator and the denominator till you arrive at the lowest form and finally compare them to determine if they are equivalent. An equivalent frac...

Chrysanthemums are a beautiful flower to have in your garden for color and for picking to take into the house. There are two very important factors with planting mums. One is that you must have the right kind of chrysanthemum and two you must plant it at the proper time. There are two types of mum plants. One is the garden center plant and the other is the mail order plant. Scott, on the video, recommends the mail order plant. The garden center plant will only last one season where the mail o...
In this video the instructor shows how to divide rational expressions. To divide rational expressions follow this simple four step approach. In the fist step change the division to multiplication by flipping the second fraction. Now the original division simplifies to multiplication. In the second step factor the terms of numerators and denominators in the two fractions. In the third step cancel the common terms in the numerator and the denominator. Now finally in the fourth step multiply all...
This video shows a tutorial of adding fractions. The first example shows a fraction that has like denominators so all you had to do is add the denominators. In the second example it shows two fractions that do not have like denominators. Therefore, you need to find the greatest common factor among the two denominators. Once this is found, you multiply the fraction on both the numerator and denominator to make both of the fractions match. Then all that is left is to add the numerators to finis...
A scale factor is a number used as a multiplier in dilation. Dilation is the act of being enlarged or minimized. Say you have a dimension of 3''. The scale factor is 2:1. So, you multiply the dimension by the scale factor to get your new dimension. After you multiply those numbers, you get 6''. Here is a link that relates to this subject. Scale Factor.
In the past few weeks, the internet has been abuzz with nightmarish horror stories of Comcast's questionable decision-making and downright terrible customer service.

A video that demonstrates one of the basic techniques involved in factorizing an equation that contains the difference of two terms which are also perfect squares themselves and are equated to 0.
In this video, the instructor shows how to multiply and divide rational expressions. To solve a rational expression that contains many terms, solve step by step by following the order of operations. Order of operations advises one to work the parenthesis part first; so solve the equation inside the parenthesis first. If you have a fraction multiplied by another fraction, first factorize the numerator and denominator of both the fractions. Cancel out any common factors simplifying it. In case ...
This a simple video illustrating the process of addition involving fractions which have common denominators. The method is really quite easy and straightforward, as demonstrated by this video. One has to simply take the denominator of the sum as the same which is the common denominator of the two fractions being added. Then, one has to take the two numerators, add the, and write their sum as the numerator of the fraction which forms the sum. Finally, the resultant fraction should be reduced b...

The photo-centric Instagram app is a great way to share "evergreen" pictures and videos when compared to Snapchat and Facebook's new Messenger Day feature. But like all social media, keeping the account secure is an essential aspect, as it restricts unwanted viewers from seeing your content and can prevent unauthorized users from accessing your account. Instagram has several methods for locking down the account including a new two-factor authentication (2FA) mechanism.

If you don't want to do this, there is an alternative. Simply mouse over the text that you have highlighted and scroll with the wheel that's on your mouse. After this, right click on the text and then you can copy what you need to. Now, you can go back to the other window you have open and paste it in, t...
In this video, the instructor shows how to collect like terms and factorize. When you are given a linear equation, the first thing you do is to try to organize it. Pair up the like terms. Add the numerical coefficients of terms with the same variables. This is called collecting the like terms. In case you see any common factor across all the terms, pull it out and tag it to the parenthesis. In this way, you can factorize the equation. Next, bunch together your like terms and sum them up. The ...

Doug Simms gives a demonstration of multiplying fraction in a simple and easy manner. The simplest problems have proper fractions to be multiplied by proper fractions, and the answer can be arrived at by simply multiplying the numerator (upper value) of one fraction with the numerator of the other, carrying out the same operation with the denominators (lower values) of the two fractions, and finally, reducing the resultant fraction by a common factor, if any. Doug also gives three other examp...
