This video gives you brief tutorial on simplifying expressions, or canceling out common factors. He starts out by answering the question "What is canceling?" and demonstrates a basic example. You find the greatest common factor between the numerator and denominator, which you then divide both by. This can also be done if you have variables in your fraction. He then shows it can be done the same way if you have binomials in your fractions. However, you must be careful that the denominator does...
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...
In this video the instructor shows how to simplify a complex fraction. A complex fraction is a fraction that has fractions in both the numerator and the denominator of the original fraction. Complex fractions can look intimidating but are generally simple to solve, as shown in this video. A fraction is nothing but a division of its numerator and its denominator. So in a complex fraction basically you are dividing two fractions. Now you can turn this division into multiplication by multiplying...
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 ...
In this tutorial the instructor shows how to solve equations with fractions and decimals. When you have a fraction first try to simplify it by canceling out the common factors in the numerator and the denominator. If there are any decimals convert them into fractions. Now if you have a number multiplying a equation apply distributive law and simplify the equation. Now finally try to get the variables on one side and numerical terms on the other side of the equation and finally solve for the u...
In this video the instructor shows who to simplify radicals. If you have a term inside a square root the first thing you need to do is try to factorize it. First factorize the numerical term. Write down the numerical terms as a product of any perfect squares. Now split the original radical expression in the form of individual terms of different variables. Now you can pull out the perfect square numerical factors out of the radical. Similarly for the variable terms write the variables as power...
In this video the instructor shows how to multiply and write rational expressions in lowest terms. The fist thing you need to do is cancel out the common factors in the numerator and the denominator. You can cancel a term in the top with a term in the bottom even if they are diagonal as long as one is in numerator and the other is in the denominator. After cancellation if you have a term in numerator and an identical term in the denominator but with opposite signs, then pull out the negative ...

In this math tutorial, you will learn how to reduce fractions using the prime factoring method. The narrator, a math teacher, of the video begins by defining what prime numbers are. This is important to know. When reducing fractions you need to reduce both the numerator and the denominator down to numbers that cannot be reduced by any other numbers but 1 and itself (prime numbers). The method the video teaches is to find the prime factors of both numerator and the denominator to simplify the ...
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...
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.

This video teaches us the method to simplify the fractions. Let us take an example of 18/24. Find a number that goes into both 18 and 24. Divide the top and bottom by the same number. Here, 2 will go into both numbers. So, the number now becomes (18/2)/(24/2) which gives 9/12. This fraction can be further simplified by dividing the top and bottom by 3. We get 3/4 which is our final answer. The fractions 18/24, 9/12 and 3/4 are called equivalent fractions since they are of the same size. Simil...
This video in the Education category will show you how to simplify radicals before adding or subtracting. By doing this you will find all like radicals which will then ensure that you have all radicals in the simplest form. Let’s say you want to subtract square root of 45 from 3 square roots of 20. Now square root of 45 can be written as square root of 9 x square root of 5. Because, 9 and 5 are factors of 45. Similarly, 3 square roots of 20 can be simplified to 3 x square root of 4 x square r...
robichaudd teaches you how to simplify square roots. When you're dealing with variables, even powers and you want to find out the square root of it, you follow the process. Divide the power by the root, which is two, because it's a square root, that gives you what comes out. If we have square root of x squared, the result would be x. So the square root of x to the 6 is x cubed. You simply divide the power by two, since we are dealing with square root. Then square root of 36 times x square is ...
