1)  Make certain that the coefficient of the x2 term is 1    ( it is )

2)  Divide the coefficient of the x-term by 2                      ( 3 divided by 2 is 3/2 )

3)  Square this answer                                                     ( (3/2)2  =  9/4 )

4)  Add this answer to both sides.

       x2 + 3x + 9/4  =  -3 + 9/4
