Solving Quadratic Equation

There are three ways to solve quadratic equations:

i-                    Factorization

ii-                   Completing Square

iii-                 Using formula

Factorization:

                If you can compute factors easily then this method is the best and the fastest. Here is an example:

Finding factors is a hit and trial method but practice makes things easy.

Cutting short the process, here are the factors:

The values of x are:

Completing Square:

                We know that:

                In this method our major goal is to achieve the above axiom, for example,

Quadratic Formula:

                For equation:
