\n" ); document.write( "(11-7i)*(2+i)
\n" ); document.write( "= x*(2+i)
\n" ); document.write( "= x*2+x*i
\n" ); document.write( "= (11-7i)*2+(11-7i)*i
\n" ); document.write( "= 22-14i+11i-7i^2
\n" ); document.write( "= 22-14i+11i-7(-1)
\n" ); document.write( "= 22-14i+11i+7
\n" ); document.write( "= (22+7)+(-14i+11i)
\n" ); document.write( "= 29-3i\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Therefore,
