Explanation:
Conversion of a quadratic equation from standard form to vertex form is done by completing the square method.
Assume the quadratic equation to be  where x is the variable.
 where x is the variable.
Completing the square method is as follows:
- send the constant term to other side of equal                  
- divide the whole equation be coefficient of  , this will give , this will give 
- add  to both side of equality to both side of equality 
- Make one fraction on the right side and compress the expression on the left side                                                                           
- rearrange the terms will give the vertex form of standard quadratic equation                                                                  
Follow the above procedure will give the vertex form.
(NOTE : you must know that  . Use this equation in transforming the equation from step 3 to step 4)
