You can put this solution on YOUR website!
$\"f%28x%29+=+x%5E2\"$ and $\"f%28x%29+=+x+%2B+1\"$
\n" ); document.write( " $\"f%28x%29+=+f%28x%29\"$
\n" ); document.write( " $\"x%5E2+=+x+%2B+1\"$
\n" ); document.write( " $\"x%5E2+-+x+-+1+=+0\"$
\n" ); document.write( "Solve anyway you know of:
\n" ); document.write( " $\"x%5E2+-+x+=+1\"$
\n" ); document.write( " $\"%28x+-+1%2F2%29%5E2+=+5%2F4\"$
\n" ); document.write( " $\"x+=+%281+%2B-+sqrt%285%29%29%2F2\"$ \n" ); document.write( "

\n" );
