I can say:
\n" ); document.write( " $\"+%28+2x+%2B+sqrt%28P%29+%29%5E2+=+4x%5E2+%2B+4%2Asqrt%28P%29%2Ax+%2B+P+\"$
\n" ); document.write( " $\"+4%2Asqrt%28P%29+=+20+\"$
\n" ); document.write( " $\"+sqrt%28P%29+=+5+\"$
\n" ); document.write( " $\"+P+=+25+\"$
\n" ); document.write( "---------------
\n" ); document.write( "Check:
\n" ); document.write( " $\"+4x%5E2+%2B+20x+%2B+25+=+%28+2x+%2B+5+%29%5E2+\"$
\n" ); document.write( " $\"+%28+2x+%2B+5+%29%5E2+=+4x%5E2+%2B+20x+%2B+25+\"$ \n" ); document.write( "
