Ok, first you need to solve the quadratic. It doesn't factor so use the quadratic formula: \"x=%28-b%2B-sqrt%28b%5E2-4ac%29%29%2F2a\"\r
\n" ); document.write( "\n" ); document.write( "\"x=%28-3%2B-sqrt%289-32%29%29%2F8\"
\n" ); document.write( "\"x=%28-3%2B-sqrt%28-23%29%29%2F8\"\r
\n" ); document.write( "\n" ); document.write( "The roots are:
\n" ); document.write( "\"A+=+-3%2F8+%2B+%281%2F8%29sqrt%2823%29i\"
\n" ); document.write( "\"B+=+-3%2F8+-+%281%2F8%29sqrt%2823%29i\"\r
\n" ); document.write( "\n" ); document.write( "To find \"1%2FA+%2B+1%2FB\" first simplify to: \"%28A%2BB%29%2FAB\"\r
\n" ); document.write( "\n" ); document.write( " = \"-6%2F8+=+-3%2F4\"
\n" ); document.write( "\"AB+=+%28-3%2F8+%2B+%281%2F8%29sqrt%2823%29i%29%28-3%2F8+-+%281%2F8%29sqrt%2823%29i%29\" = \"9%2F64+-+%281%2F64%29%2823%29i%5E2\" + \"9%2F64+%2B+23%2F64+=+32%2F64\" = \"1%2F2\"\r
\n" ); document.write( "\n" ); document.write( "Finally, \"%28A%2BB%29%2FAB+=+%28-3%2F4%29%2F%281%2F2%29\" = \"%28-3%2F4%29%282%29+=+-3%2F2\"
\n" ); document.write( "
\n" ); document.write( "
\n" );
