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...

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...
