\n" ); document.write( "\n" ); document.write( "OK, YOU ARE ABSOLUTELY RIGHT: SO LETS USE THE CONJUGATE AND WHAT THIS WILL DO IS GET RID OF THE RADICAL IN THE DENOMINATOR (AS YOU KNOW, THE CONJUGATE OF 1+i IS 1-i.\r
\n" ); document.write( "\n" ); document.write( "((3-i)(1-i))/(1+i)(1-i))
\n" ); document.write( "The numerator reduces to(using FOIL: First, Outer, Inner, Last):\r
\n" ); document.write( "\n" ); document.write( "3-3i-i+i^2 (i^2=-1) so we have for the numerator:\r
\n" ); document.write( "\n" ); document.write( "3-4i-1=2-4i
\n" ); document.write( "For the denominator we have:\r
\n" ); document.write( "\n" ); document.write( "1-i+i-i^2; (-(i^2))=(-(-1))=+1 so we have\r
\n" ); document.write( "\n" ); document.write( "1+1=2 \r
\n" ); document.write( "\n" ); document.write( "Putting the numerator and denominator back together, we have:
\n" ); document.write( "(2-4i)/2 divide numerator and denominator by 2 we get:\r
\n" ); document.write( "\n" ); document.write( "1-2i-------------------ans\r
