You can put this solution on YOUR website!
i must just add to this, sorry...\r

\n" ); document.write( "\"x%5E2+=+12\"
\n" ); document.write( "x= +- \"sqrt%2812%29\"
\n" ); document.write( "x=+\"sqrt%2812%29\" or x=-\"sqrt%2812%29\"\r
\n" ); document.write( "\n" ); document.write( "Whenever you take a square root, ALWAYS remember the negative version too! It is VERY important.\r
\n" ); document.write( "\n" ); document.write( "As for simplifying root12....\r
\n" ); document.write( "\n" ); document.write( "\"sqrt%2812%29\" is \"sqrt%284%2A3%29\"
\n" ); document.write( "\"sqrt%284%29sqrt%283%29\"
\n" ); document.write( "\"2sqrt%283%29\"\r
