Substitute $\"-%281%2F2%29\"$ for all occurences of $\"x\"$ and simplify
\n" ); document.write( " $\"P%28x%29+=+2x%5E4+%2B+x%5E3+%2B+12\"$
\n" ); document.write( " $\"P%28-1%2F2%29=2%28-1%2F2%29%5E4%2B%28-1%2F2%29%5E3%2B12\"$
\n" ); document.write( " $\"P%28-1%2F2%29=2%281%2F16%29-%281%2F8%29%2B12\"$
