How to Complete the square

Quadratic equations are easy to solve when they can be factorized. This video teaches another method of solving a quadratic equation when its not easy to find factors for it. The method to do so consists of adjusting the C term (a normal quadratic equation is of the form Ax^2 + Bx + C) by manipulating the equation itself. By adding a calculated value to both sides of the equation, the terms on the left hand side may be reduced to a perfect square (Hence it is named the method of perfect squares). The equation can then be easily solved using basic arithmetic manipulation.
