You can put this solution on YOUR website!
$\"+z%5E2+-+100+=+0+\"$
\n" ); document.write( " $\"+z%5E2+=+100+\"$
\n" ); document.write( " $\"+z+=+sqrt%28+100+%29+\"$ and
\n" ); document.write( " $\"+z+=+-sqrt%28+100+%29+\"$
\n" ); document.write( " $\"+z+=+10+\"$
\n" ); document.write( " $\"+z+=+-10+\"$
\n" ); document.write( "---------------------
\n" ); document.write( "I notice that:
\n" ); document.write( " $\"+2%2A25+=+50+\"$ and
\n" ); document.write( " $\"+2+%2B+25+=+27+\"$
\n" ); document.write( "Using this:
\n" ); document.write( " $\"+y%5E2+%2B+27y+%2B+50+=+%28+y+%2B+25+%29%2A%28+y+%2B+2+%29+\"$
\n" ); document.write( " $\"+%28+y+%2B+25+%29%2A%28+y+%2B+2+%29+=+0+\"$
\n" ); document.write( " $\"+y+=+-25+\"$ and
\n" ); document.write( " $\"+y+=+-2+\"$
\n" ); document.write( "----------------
\n" ); document.write( "check:
\n" ); document.write( " $\"+y%5E2+%2B+27y+%2B+50+=+%28-25%29%5E2+%2B+27%2A%28-25%29+%2B+50+\"$
\n" ); document.write( " $\"+625+-+675+%2B+50+=+0+\"$
\n" ); document.write( "OK
