$\"f%28x%29=2x%2F%284x%5E2+-2x%29\"$
\n" ); document.write( "First let's simplify,
\n" ); document.write( " $\"f%28x%29=2x%2F%282x%282x-1%29%29\"$
\n" ); document.write( " $\"f%28x%29=1%2F%282x-1%29\"$
\n" ); document.write( "The denominator cannot equal zero.
\n" ); document.write( " $\"2x-1=0\"$
\n" ); document.write( " $\"2x=1\"$
\n" ); document.write( " $\"x=1%2F2\"$
\n" ); document.write( "x can be any value except x=1/2.
