If the expression is \"%282%2B3i%29%2B%28-4%2B5i%29-%289-3i%29%2F3\", then...\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"%282%2B3i%29%2B%28-4%2B5i%29-%289-3i%29%2F3\" Start with the given expression.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"%282%2B3i%29%2B%28-4%2B5i%29-%289%2F3-%283i%29%2F3%29\" Break up the fraction\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"%282%2B3i%29%2B%28-4%2B5i%29-%283-i%29\" Reduce.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"2%2B3i-4%2B5i-3%2Bi\" Distribute\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"-5%2B9i\" Combine like terms.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So \"%282%2B3i%29%2B%28-4%2B5i%29-%289-3i%29%2F3=-5%2B9i\"
\n" ); document.write( "
\n" );
