It would be undefined if the denominator is zero, so:
\n" ); document.write( "m^2-49 = 0
\n" ); document.write( "m^2 = 49
\n" ); document.write( "m = +- 7
\n" ); document.write( ".
\n" ); document.write( "So, it is undefined if
\n" ); document.write( "m = -7
\n" ); document.write( "or
\n" ); document.write( "m = 7
\n" ); document.write( "
\n" ); document.write( "
\n" );
