\n" ); document.write( "\"v=4x-x%5E2\"
\n" ); document.write( "\"v=x%284-x%29\"
\n" ); document.write( "max at \"v=0\"
\n" ); document.write( "\"0=x%284-x%29\"
\n" ); document.write( "=>\"x=0\"->disregard
\n" ); document.write( "\"0=%284-x%29\"=>\"x=4\"\r
\n" ); document.write( "\n" ); document.write( "answer is \"4m%2Fs\"
\n" ); document.write( "
