A Quadratic Equation is an polynomial equation with highest degree 2. For e.g.: 5x 2 + 2=0 2x 2 + x + 1=0 General form of the equation is: ax 2 + bx + cx = 0 where a is not equal to 0 Normal form of Quadratic equation can also be represented by two parameters. (say m and n) x 2 + mx + n = 0 Normally , We are asked to find the roots of the equation. The roots of the equation can be found using three methods. Let us take the example x 2 -6x + 8=0 and solve this equation using these methods separately. Let's Start: 1.) The Grouping Method or that's what i call it In this method we try to split the middle term or 'b' such that it is equal to the product of the rest of the terms or 'ac'. Now, let us apply this method on the above equation. x 2 -6x + 8=0 As, it is easily visible, the term -6 has to be split in a such a way that it's product equals to 8. x 2 -6x + 8=0...
