How To: Simplify expressions involving numeric radicals

In this video tutorial, viewers learn how to simplify expressions involving numeric radicals. This can be very frustrating to work with if you have not memorized the tables of square, cubes and fourths. If you are taking the square root of a number that is not a perfect square and you wish to simplify it, the key is to write it as the product of a perfect square or another number. This video is very descriptive and clearly explains the functions of the formula. This video will benefit those v...

How To: Alter a pre-existing quilt

Try a quilting experiment to make a radical change to your hand crafted quilt. In this video, the original quilt was much larger, and has been cut down to groups of 9 blocks. See how a different swath of fabric is sewn right through the center of the quilt.

How To: Use the quadratic formula to solve algebraic equations

Using the quadratic formula to solve equations may bring one, two, or no algebraic solutions. 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...

How To: Multiply and simplify square roots

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...

How To: Graph half an ellipse

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...

How To: Simplify rational expressions

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...

How To: Draw a surfboard with cool designs

Michael Weisner, professional illustrator and animator, guides you step by step through designing a surfboard. Michael shows us in just a few steps how to draw the basic shape of a surfboard, and then how to add a radical surf-themed design to our creation. Using his example in this video, even the least artistic of us can get a feel for how to design the art for a surfboard. His example includes a moon, a Tiki man and flames. Gnarly!

How To: Understand and work with rational & irrational numbers

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...

How To: Understand nth roots and operations on radicals

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...

How To: Solve square roots in algebra

In this lesson we will learn about one of the most important concepts in algebra SQUARE ROOTS. The square root of a number m is another number n that satisfies the following formula: m = n x n. You can also say that m is the square of n. The opposite of squaring a number is finding its square root. You can use the radical symbol to indicate that the square root of m is n:
