A factoring problem that has to be solved by grouping is easy to identify, because you can always identify if there are any similar terms in a polynomial. Now, if you find any variable common in any terms pull them out as the common leaving the rest of the terms. After pulling out the common terms you can group the rest of the polynomial. Be careful while pulling out signs. Pulling out a positive number does not effect the signs of terms in the polynomial, where as pulling out a negative numb...
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 shows the method to add rational expressions with different denominators. The first step in this process involves finding the LCD. After this is done, the numerator and denominator are multiplied by a specific number so that the fractions are rewritten with common denominators. In the second step the numerators are added or subtracted according to the problem with LCD in the denominator. Simplify the numerator by adding or subtracting like terms. After this, we get a rational expre...
The video describes the basic process of multiplying two rational expressions. The problem illustrated in this video involved multiplying rational expressions of monomial terms with integer coefficients. As with the other example problems, we follow the steps of: factoring, canceling, and multiplying. Because these terms are monomials, no factoring is required (but we still state it as a step for similarity to solving other problems). We then find the greatest common divisor for both terms to...
One can learn, from watching this video, how to multiply and divide fractions. Prof. Alexander gives a discourse on multiplication and division of fractions in a simple, easy way. For multiplication, one should first look for highest common factor in the numerator of one fraction and the denominator of the other, and vice versa, and if found, carry out the reduction by that factor. Then the numerator of one fraction is multiplied by that of the other fraction, the same operation is carried ou...
This video will show you how to carry out multiplication of fractions using cancellation, which will make your fraction multiplication problems simpler to solve. You will need to look at the numerator of the first fraction and the denominator of the second fraction and see if you can find a common factor between the two numbers. If one does exist, you can simply divide both numbers by that common factor and simplify. Repeat this for the other numerator and denominator and if possible, your fr...
This video teaches you how to use APT (Arbitrage Pricing Theory) models and formulas. This video shows two specific parts of the APT models the first being the after the fact version and the before the fact version. The before the fact version is focused on as being the most important which is used to calculate expected returns to calculate risk. It is discussed how flexible this model is and how different factors can be moved in and out of the formula and how each different factor is used. T...
What Is Scale Factor? Scale factor is the ratio of the length of the scale drawing to the corresponding length of the original object.

Try Betty's tasty steak dish with horseradish brown gravy. This looks absolutely amazing. Play special attention to her description of the cuts and the ingredients.
This video is a demonstration of how to cook a perfect steak. She explains how to sear a steak in a cast iron skillet. She turns the burner on pretty high. She explains that a non-stick pan doesn't work well for this recipe, because a cast iron skillet is better for high heat. She uses a rib eye steak and takes it out of the fridge 20 minutes before cooking so it won't be cold when it goes into the pan. She sprinkles the steak with salt, and freshly ground pepper. She puts unsalted butter int...
This is a walkthrough of the hunt for our solar system and home planet Earth. The searching is fast forwarded. Saw a picture on the net of a vague location of where it might be. This is an Easter egg in Spore.
Two-factor authentication (also known as 2FA) adds a necessary additional layer of security to your username and password in many important apps. On Instagram, 2FA requires you to confirm it's you attempting to log in, with a special code sent to you via text message. Enter the code and you're in ... but what happens when you need to log in and don't have access to your phone?
If you didn't get the memo, passwords aren't enough protection for your online accounts. Even a long and complex password offers only one line of defense which can falter. Two-factor authentication adds an additional layer, bolsters your defense, and decreases the risk of your account becoming compromised.

In this tutorial, we learn how to cook delicious earth friendly trout. First, throw 4 tbsp butter in a saucepan and then juice 2 tbsp lemon juice. From here, grab some fresh chopped Italian parsley. Once the butter is a golden brown color, it will be finished melting. After this, you will turn the heat off and then take 1/2 tsp and spread it on your boneless rainbow trout. Then, sprinkle on salt and pepper and place under a preheated hot broiler for a couple of minutes. Trout cooks very fast,...

In this video, an expert gardener explains how to propagate raspberries and blackberries.To propagate, you normally need a small rooted cutting. The expert recommends that you soak the roots in water with a bit of root stimulator for about 15 minutes. Also, he says that the cutting should be planted in earth with compost and phosphorous fertilizer to help to roots grow better. When the earth is well mixed, you make a small hole, place the root in side and bury it, pressing the soil around the...

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.
