Algebra.Com's Answer #535221 by Theo(13342)![]() ![]() You can put this solution on YOUR website! if the equation is 7th degree then it has 7 roots. \n" ); document.write( "those roots can be complex or real. \n" ); document.write( "complex roots always come in pairs, so if it has one, then it has 2, the other one being the conjugate of the first one. \n" ); document.write( "in other words, if one complex root is a + bi, then the other complex root is a - bi. \n" ); document.write( "if at least one root is complex, then you would have a minimum of 2 complex roots with a maximum of 5 real roots. \n" ); document.write( "the equation can have at most 6 complex roots (3 pairs) so the minimum number of real roots is equal to 1.\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
