\n" ); document.write( "\n" ); document.write( "By distributive property
\n" ); document.write( "5i(4-2i)
\n" ); document.write( " $\"20i+-10i%5E2\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Remember that $\"i%5E2=-1\"$
\n" ); document.write( " $\"20i+-10i%5E2\"$
\n" ); document.write( " $\"20i+-10%2A%28-1%29\"$
