In this video the instructor shows how to solve a system of equations by elimination method. First you need to know how many possible number of solutions you can get by solving a system of equations. There are three possibilities. In the first case there are two lines with different slopes, so they intersect at a point which is the solution to that system. In second case there can be two lines with same slope but are parallel to each other. In this case the system has no solution. In the thir...

System of equations is nothing but a system which contains more than one linear equations. This system of equations can be solved to arrive at the solution of the system. A simple system of the linear equations can be a pair of equations. To solve this kind of system you can employ the substitution method. So take the two equation of the system. Solve for the value of y in the first equation in terms of x. Now take this value of y and substitute in the second equation y value. Now the second ...

To solve simple algebraic expressions you have to use different properties. Distributive property is one among them. To apply distributive property in a algebraic expression multiply each term inside the parenthesis by the outside term. In this way you are distributing the outside term to all the inside terms and removing the parenthesis. Hence it is called distributive property. After multiplying add the like terms to simplify it further. Care should be taken to ensure the proper sign change...

In this video tutorial, viewers learn how to make "hot ice". Begin by adding water into a pan and heat it until it’s simmering, but not boiling. Add the sodium acetate to the water. Keep adding the sodium acetate until the water cannot dissolve it anymore. Stir constantly. Now pour the solution into a glass or container. Do not pour in any undissolved crystals. Place the solution into the refrigerator for 45 minutes. Now pour the solution into a container. The liquid will instantly turn into ...
artjewelrymag teaches you how to use a liver of sulfur solution to create a patina. First, be sure to wear protective gloves and eye gear. Be sure to perform this operation in a well-ventilated area because sulfur smells like rotten eggs. To get started, add a few small pieces of liver of sulfur to a small dish of warm water. Use a wooden stick or a small PVC pipe and stir. The temperature and the amount of time you leave the metal in the solution will affect the patina. You can dip the metal...

In this video the instructor shows how to factor a general quadratic polynomial. Here the first step is to identify the coefficient of the squared term. Write the reciprocal of the numerical coefficient of the squared term out side and write two separate parenthesis which are going to contain the binomials which are the factors of the original equation. The first term of both the binomials is the first term numerical coefficient times the unknown variable. Now multiply the first term numerica...
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 tutorial the instructor shows how to identify similar terms in a polynomial equation. He states that in similar terms the variables and their exponents are exactly the same but they may differ in the co-efficient. He shows how to identify similar terms by using some examples. He shows that a change is even the co-efficient makes them dissimilar terms. Similar terms can be further added as the variable of both the terms is same. This video gives an idea of what similar terms are and ho...
Want to make boring old colorless water brighten up on command? Well, you can control the color of water with this little magic trick. Actually, it's not really magic, but a classic science experiment known commonly as the iodine clock reaction, which uses the reactions between water and chemicals to instantly colorize water, seemingly by command. You can use different colorless chemicals to produce different colors, and you can even make the color vanish to make the water clear again.

He then gives some examples of differential equation and explains what the equation's order means. After that he gives an example on how to solve a simple equation. He calculates it and gives examples of graphs. Then he explains what a general solution is and how to narrow down the number of solutions using data from the pr...
Multiplying polynomials is a distributive property. If you are given with two binomials and asked to multiply them, you need to apply the distributive property and multiply the terms of binomial with the terms of second binomial. To do this first take a term of first binomial and multiply it with the second complete binomial. Now take the second term of first binomial and multiply it with the second binomial adding or subtracting it from the previous result depending on the sign between the f...
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 order to solve a quadratic equation by completing the square, take a quadratic equation and make sure that the coefficient of the first squared term in one. If it is not factor it by pulling the term out to get it to one. Now just write down the first two terms in side a bracket and after it add the third term. Now take the coefficient of the x term and take one half of it and square it and put that number back into the bracket. Now as you added a new number, to cancel it out subtract it f...
