Complex zeros come in conjugate pairs. So 2i is paired with -2i.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "This means that the zeros are 2, 31/2, 2i, -2i. \r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Since there are 4 zeros, this means that the lowest degree is 4.
