In this video the instructor shows how to add and subtract rational expressions. When you have an addition or subtraction problem of rational expressions, first look and compare the denominator of all the terms. If all of them have the same denominator then the expression can be written as a fraction whose denominator is the original common denominator and whose numerator is the sum of numerators of all the other terms. Simplifying the numerator by adding and subtracting the like terms gives ...
In order to solve a quadratic equation by completing the square, take a quadratic equation and make sure that the coefficient of the first squared term in one. If it is not factor it by pulling the term out to get it to one. Now just write down the first two terms in side a bracket and after it add the third term. Now take the coefficient of the x term and take one half of it and square it and put that number back into the bracket. Now as you added a new number, to cancel it out subtract it f...
To simplify a complex fraction, turn it into one fraction on the top divided into a fraction on the bottom. Once this is complete, you will turn the division into the two into a multiple by the reciprocal, factor, and then cancel. To make a division, find the lowest common denominator of both the top and the bottom. Once you get this division equation, look carefully at the equations. If something can be easily canceled, go ahead and cancel it out at this time. If you cannot cancel anything a...

This is a mathematical instructional video on how to find the least common multiple. Let us now find the least common multiple for 25, 100, 18. This can be written as 5 square, 2 square multiplied by 5 square, 2 multiplied by 3 square. The highest factor in these numbers are, 5 square, 2 square and square. If you multiply 5 square with 2 square and 3 square you will get the final answer as 900. This is the least common multiple of 25, 100, and 18. This method is explained very clearly in this...
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...
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...
Watch this video to learn how to multiply fractions by fractions. First multiply the top numbers together. For example, if you have 3/5 * 4/7, multiply 3 * 4 and put your product on top of the fraction you will get as a product. Next, multiply the bottom numbers together and put them on the bottom of your resulting fraction. Next see if you can reduce your product to simplify it. You could also do the reducing step first by canceling out any common factors in the numerators and denominators o...
The distributive property is a very important factor to consider in math and may save you a lot of trouble on your math homework. For values which lie right outside parentheses, you will need to distribute this value across the contents of whatever is inside the parentheses. You will need to multiply the value outside of the parentheses by first the first term inside the parentheses and then by the following terms inside the parentheses, distributing the value across all the terms found insid...
Calluses can become a big problem for weightlifters, which is caused by not wearing gloves when you're lifting weights. The friction between the hand and the bar caused by the movement and weight is the factor for getting a callus. Easy way to remove them is using a product called Calluses and scab remover. Apply liberally to spots making sure not to miss any spots. Allow to sit for one to two days and then presto you should see that your calluses have regressed or disappeared completely.
Doug Simms online shows how to simplify the radical in a mathematical equation. If you need to brush up on your learning this video can help. Start by finding what is the largest square of the number in your radical. If that number can be solved then solve it, put the answer outside the box and the remainder in the radical. There are some great examples to follow including what to do if your number has a solution, or if there are two factors that your equation can create.
While dividing the radicals, the numerator and the denominator must be combined into a single term, for example if we want to divide square root of 3 by square root of seven we need to combine the numerator and denominator into a single factor that is square root of 3/7, then we can divide 3/7 which is 0.4285, and square root of 0.4285 is 0.654 which is the final answer.

One thing that can really set a amateur from a pro when it comes to poker is the ability to read your opponent. Picking up on "tells" from your opponent can be the key from folding your hand or making that extra bet to take the pot. One of the main keys they factor on is that you need to take into affect the possible strength of your opponents hand and your position on that opponent. Good players do not win on a consistent basis just from getting good hands. While it takes much practice if yo...
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...

In this video tutorial by Dr Suzann Wang you will learn how to prevent gastroesophageal reflux disease (GERD). It is a hyper or low acidity problem in the stomach. The ph factor measures the acidic or alkaline nature of anything and it has a range of 0 to 14; 14 being highly alkaline and 0 being highly acidic. The stomach acidity tends to be 2. 0 which is pretty acidic. The acidity should be 2. 40. If the acidity is lower, it affects the rest of the digestive system. You can rectify this by t...
This video from Your Teacher is one of a range of math solutions. (which is the measurement from the center to the edge when drawn in a straight line) and also the area of the circle, is the amount of total space within its perimeter. The circumference of this circle is 20 pi. The circumference is 2 pi r. So 20 pi is 2 pi r. Which factors down to show that 10 is the radius (10=r). The area is pi r squared. As we know the radius is 10, we can work out the area - 100 pi.
Computer forensics expert Steve Burgess gives a highly informative tutorial on how to recover deleted emails in Outlook and Eudora. The most critical factor affecting the recoverability of deleted web-based emails, according to Steve, is whether the PST file, which stores all the emails, has been compressed after the mail was deleted.
