Algebra.Com's Answer #393227 by jim_thompson5910(35256) ![]() You can put this solution on YOUR website! 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. \n" ); document.write( " |
