In this video the instructor shows how to solve quadratic equation by the square root method. The square root property of equations states that if k is positive and a*a = k, then a is equal to square root of k or -1 times the square root of k. So to solve a quadratic equation by square root property first get the equation in the form of a*a = k. Now apply the square root property explained in the previous step to get the result. The instructor now demonstrates these concepts by solving some e...
The gentleman, acting as the Instructor, starts the session immediately by suggesting that to teach early multiplication all parents should practice a method of "Count-by's" with their children when they are very young using ones to ten, twos to twenty, threes to thirty, fours to forty, and so forth. The Instructor then demonstrates this method of counting by tens using a grid behind him on a chalkboard which depicts columns of ten elements. He counts each column from 10 to 100, and then writ...
This is a demonstration on how to use the PLL method to solve a Rubik's cube. The author informs that what people do before and after applying the PLL technique is very important. According to him, people usually tend to first align as many faces as they can, when they see a partial algorithm and then apply the PLL method, which is very time consuming. Instead, one should stop one step short of alignment, apply the Pll method and then align the faces completely. The author, however, points ou...
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...

Elimination in mathematics is used to find the solution set of a system of equalities. This video tutorial shows how to use elimination to find the solution set of a given equation and offers several examples to illustrate the process. Before applying this method, the equation must be in the form “Ax +By=C.” When graphing a set of mathematical equations that intersect, the answer to the elimination is the point on the graph where the two lines cross.
