\"%287-6i%29%2B%289%2B11i%29\"
\n" ); document.write( "Multiply like any 2 binomials
\n" ); document.write( "----------
\n" ); document.write( "= 7*(9+11i) - 6i*(9+11i)
\n" ); document.write( "= \"63+%2B+77i+-+54i+-+66i%5E2\"
\n" ); document.write( "= 63 + 23i + 66
\n" ); document.write( "= 129 + 23i
\n" ); document.write( "
\n" );
