Algebra – The Distance Formula.
In this tutorial we learn how to multiply and simplify square roots. When you multiply square roots, you will first need to put them under one radical. From here, you will need to factor out what you have. Once you find a perfect square, find the square root of it. You can either write these as all separate equations or pull the perfect root on the outside of the other parts of the equation. Do the math until you find what you are left with. From here, you can do basic math to find what's lef...

The quadratic formula is special to quadratic equations, which can have fractions, radicals, or neverending decimals. Learn how to solve quadratic equations using the quadratic formula with this free video algebra lesson. 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 ea...
If you are given an equation of ellipse in the form of a function whose value is a square root, you may need to simplify it to make it look like the equation of an ellipse. Now equate the function to a variable y and perform squaring on both sides to remove the radical. Now simplify the equation and get it in the form of (x*x)/(a*a) + (y*y)/(b*b) = 1 which is the general form of an ellipse. Now you will have the x and y intercepts which are a and b respectively. Using this values graph the eq...
When you need to compute the square root of a number you can do it by breaking it into perfect squares. When you can split the given number into small perfect squares you can cancel out the square root of the expression to the square of the perfect squares. You cannot always write the number inside the square root as a perfect square, but try to write this number as a product of a perfect square and another number. Now you can pull out the perfect square out of the radical and leave the remai...

Esther-Xiaohu will give you what you need to recognize these water words in print today!
In this video the instructor explains the concepts of rational and irrational numbers. Multiplying a number by itself gives the value of its square. If you apply the square root to that squared number it returns to you the original number. This square root is also called a radical. A square root of a positive number can have two values. For example the square root of 81 is either 9 or -9; this is because when you multiply 9 with itself the square is 81 and even when you multiply -9 with itsel...
Whenever you simplify a square root or a cube root you are writing them in the simplest form. This video teaches a factoring method.

This video tutorial is in the Home & Garden category which will show you how to contain your sheep with hurdles. For this project you will need thin and long wooden staffs. This can also be done with bamboo. Split the wooden staffs in half. Take a heavy piece of timber and make holes in it at regular intervals. Place the timber at the boundary of the area where you want to contain your sheep. Then drive one unsplit wooden staff through each hole in the timber so that the end of the staff gets...
In this video the instructor shows how to divide rational expressions that contain trinomials. A division containing two fractions can always be turned into a multiplication by multiplying the first fraction by the reciprocal of the second fraction. This way any division can be turned into a multiplication problem and solved easily. Now after you convert the division into multiplication factorize the equations. Now you can factorize the equations by splitting the middle term and grouping it i...
Despite what its name would naturally suggest, the chocolate egg cream drink doesn't actually contain any eggs...or cream. It does, however, contain chocolate (thankfully). The chocolate egg cream is actually a chocolate soda (thank the heavens for such an invention) that's not well known outside of New York, though we're it soon will be.

In this video tutorial, Chris Pels will show how to persist and restore information in the ViewState of a custom user control. First, learn how to persist simple values containing .NET primitive types such as String, Int32, Boolean, etc. Then see how to persist complex types such as Class which contain properties storing information. The sequence of processing View State information during the lifecycle of an ASP.NET page is also discussed.
Try your hands at duck eggs instead of chicken eggs. Duck eggs are practically the same, a little bit larger than chicken eggs, but the yolks contains a lot more fat (making them richer) and the whites contain a lot more protein. They're perfect for baking because they make desserts light and fluffy! But forget about dessert— we're talking pizza here.
This card trick is called Serenade of the Kings. Make two piles of four cards. The first pile contains all kings, and we set these face down (except for the leader king in front) on the table in a star shape. The other pile contains four black spot cards that help us do our magic. Burying the kings into the black spot cards, one by one, shows that they disappear into the pile with a little twist and shake. Now we place the kings and black cards in four different piles of two, but once we pick...
Check out these educational videos for veterinarians and curious eyes on the anatomy of the male reproductive tract in the bull. Here you will see, in three parts, the scrotum of the bull, which contains both of the testes. The scrotum is a thinner skin area of the rest of the beast, with less hair. Upon dissection of the male bovine scrotum, you will see the tunica dartos muscle and some stratum tissue. The testes is the structure that contains the sperm producing cells.
This video teaches us the concept of nth roots. The video starts with the square root of constants. We find the number which when multiplies by itself for two times results in the constant inside the square root. Then we find the square root of variables. Here again the same concept is used. We find the variable which when multiplied by itself for two times results in the given variable. Then we find the cube root. Here we find the number which when multiplied by itself for three times result...
