Step 1: Note-down the given quadratic equation and compare it with the standard form ax^2 + bx + c


EXAMPLE: x^2\ +6x\ +11        

                  ax^2 + bx + c

Where a = 1, b = 6 and c = 11


Step 2: Substitute all the values in the discrimination( b^2-4ac ) of the equation.

b^2\ -\ 4ac\ = 6^2-\ 4\ \cdot1\cdot11

                  = 36 - 44

                  = -8
