The expression $\"%28m%5E2-2m-3%29%2F+%28m%5E2-10m%2B21%29\"$
\n" ); document.write( "has no value when $\"m%5E2-10m%2B21=0\"$ ,
\n" ); document.write( "and since $\"m%5E2-10m%2B21=%28m-7%29%28m-3%29\"$ ,
\n" ); document.write( " $\"m%5E2-10m%2B21=%28m-7%29%28m-3%29=0\"$ if and only if $\"m=7\"$ or $\"m=3\"$ .
\n" ); document.write( "Those values of $\"m\"$ are excluded.
\n" ); document.write( "
\n" ); document.write( " $\"m%5E2-2m-3=%28m%2B1%29%28m-3%29\"$ ,
\n" ); document.write( "so for $\"m%3C%3E3\"$ ,
