Below are the choices:

-1/2
0
 -1
 non

The  exclusions are placed on the variable x for the fraction 4x^2-1/4x+2 is -1/2. Below is the solution, 

4x+2 = 0 so 4x=-2 so x=-2/4 wich is -1/2
4x + 2 = 0

so , 4x  = -2

Based on this, you will get that the x would be  : -2/4     = -1/2

Hope this helps
