(8 - i)/(1 - 2i)
\n" ); document.write( "------------------
\n" ); document.write( "Multiply the NUM and DEN by the conjugate of the DEN, 1 + 2i
\n" ); document.write( "\"%288+-+i%29%2A%281+%2B+2i%29%2F%28%281+-+2i%29%2A%281+%2B+2i%29%29\"
\n" ); document.write( "= \"%288+%2B+15i+-+2i%5E2%29%2F%281+-+4i%5E2%29\"
\n" ); document.write( "= (10 + 15i)/5
\n" ); document.write( "= 2 + 3i
\n" ); document.write( "
\n" );
