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...

Michelle Phan presents this tutorial video on caring for your skin with champagne. You can use less than a sip of your champagne as a detoxifying cleanser/ toner.
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...

The Galaxy Note 10 is a radical departure from what Samsung has traditionally done with past releases. The most noticeable change is the fact that there are four distinct variants. But Samsung also turned the power button on the Note 10 into a Bixby key, which means powering the phone off or rebooting it is a bit different.
While change is good, it isn't always welcomed. All software updates with radical redesigns and brand-new features bring at least a few complaints from those accustomed to previous versions. iOS 7 got a lot of flak from iOS 6 users, as did iOS 8 from iOS 7 users.
Windows 8 the biggest update to Windows yet. The new gesture-friendly version replaces the aging start menu with a dynamic new Start Screen, complete with live tiles that give you a glimpse into your apps before you launch them, not unlike the new Windows phones. With such a radical departure from the past, some familiar features have been moved around, which will take some getting used to. It's worth noting that the new Windows 8 does not abandon the old desktop model completely; it still ha...

Microsoft recently released "Seeing AI," an app aimed to help the blind understand their surroundings. As Microsoft puts it, "the app narrates the world around you by turning the visual world into an audible experience."
The emerging narrative as CES begins is that consumer-grade smartglasses require a heavy compromise in functionality in order to arrive at a form factor and price point that appeal to mainstream customers.
Samsung has legions of loyal fans, and for good reason — their Galaxy S lineup ticks so many boxes that it would be a downgrade to switch to any other phone. Though if you're still rocking an older model like the Galaxy S7 Edge, the all-new Galaxy S9 can tick all the same boxes plus a few more. But is it worth the money to upgrade at this point? That's actually a tougher call than you might think.
