You can put this solution on YOUR website!
You need to also have as zeros the conjugates of those numbers: \"5%2Bi\" and \"-sqrt%2817%29\".
\n" ); document.write( "That way, when you multiply factors involving conjugates, the irrational/imaginary parts cancel out.
\n" ); document.write( "Your polynomial must be of grade 4, and the one with a leading coefficient of \"1\" can be calculated as:
