Write, as a complex number, in standard form (a+bi):
\n" ); document.write( "\"2i%284%2Bi%29\" Apply the distributive property'
\n" ); document.write( "\"8i%2B2i%5E2\" But \"i%5E2+=+-1\", so...
\n" ); document.write( "\"8i%2B2%28-1%29\" Write in standard form.
\n" ); document.write( "\"-2%2B8i\" or \"-2%281-4i%29\"
\n" ); document.write( "
\n" ); document.write( "
