In order to simplify complex variables, you must first consider the numerical values separate from the variable. In the case of 24x/48x, you would look at the numbers alone to see if they have any factors. These numbers have the number 6 in common. So, divide it by 6. This will give you 4/8. This still requires some simplification. Two is still a factor for both. So, divide it again by four. This will give you 1/2. Now, if the numerator was raised to the second power, in the original equation...
Single crochet stitches sound easy, but when many are knitted together into a pattern you get a very thick and heat-resistant surface. That's the idea behind this simple beginner-level crochet project for crafting a granny-style potholder out of a single crochet stitch.
Learn how to take a quadratic equation in standard form and change the trinomial into a binomial product. Using the zero product rule, the zeros of the graph can then be found. The grouping method is effective when the leading coefficient (the number factor of the squared term) is some number other than 1 (one). From Ramanujan to calculus co-creator Gottfried Leibniz, many of the world's best and brightest mathematical minds have belonged to autodidacts. And, thanks to the Internet, it's easi...
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...
Don't get us wrong - we love Valentine's Day. After all, it's the one day of the year you can lay everything down on the line and tell someone "I love you" earnestly. But if you happen to be single on Valentine's Day, the occasion can seem more S.A.D. (Single's Awareness Day) than all hearts and roses.

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.
As great as the Internet is, it is not without its dangers. Hackers at any time may be breaking into your online accounts and compromising your sensitive information. Last year, hackers broke into Facebook, Gmail, and Twitter and made off with 2 million stolen passwords.
In this video, Sierra Snowboard gives us some tips on how to select the snowboard that's right for you. Each board comes in a number of different sizes, and most boards come with a size chart specific for that board. These charts can be vague, but are good starting points for selecting your size. One thing to consider is your bossy type. The weight of the rider is the primary factor in selecting the size of a snowboard. You'll notice that the height of a rider is not listed on a size chart. I...

Donna teaches how to do a front-post, back-post crochet stitch. First of all you'll need yarn and a hook. Start with a single crochet. Donna uses white to create the single crochet and to create a heart, goes over the single line with pink to create a double crochet. To create the double line, go around and through. from front to back, through the single post. Always have the yarn going through the same side. The basic method using the pink, is to make the design in a "V" shape. Using this me...
The method demonstrated in this how-to video makes the Bowline knot quick and easy to tie. It is useful when you expect a blow and need to take a few turns around your winch to use as an additional hardpoint. In this case I am simulating a mast winch but the process can be used on a horizontally mounted winch as well. The secret is to form the bowline eye by capsizing an overhand knot. With the standing part in your left hand form a turn around the winch from top to bottom then cross the runn...
