2x/(4x^2-2x)
=2x/2x(2x-1)
=1/(2x-1) restrictions on the variable: x cannot be 1/2 because that would cause division by zero which is not allowed.

f%28x%29=2x%2F%284x%5E2+-2x%29
First let's simplify,
f%28x%29=2x%2F%282x%282x-1%29%29
f%28x%29=1%2F%282x-1%29
The denominator cannot equal zero.
2x-1=0
2x=1
x=1%2F2
x can be any value except x=1/2.
