\n" ); document.write( "\"H+=+-5%28t-3%29%28t%2B5%29\"\r
\n" ); document.write( "\n" ); document.write( "Set \"H=0\" for ground height, then solve for\"+t\"\r
\n" ); document.write( "\n" ); document.write( "\"0=+-5%28t-3%29%28t%2B5%29\"\r
\n" ); document.write( "\n" ); document.write( "if \"0=+%28t-3%29\"=> \"t=3\"
\n" ); document.write( "if \"0=+%28t%2B5%29\"=> \"t=-5+\"=>negative zero is not meaningful in this situation, so disregard it\r
