Algebra.Com's Answer #299470 by tinbar(133)![]() ![]() ![]() You can put this solution on YOUR website! in general, using the fundamental theorem of algebra, you can conclude that any polynomial of degree n has n solutions (including multiplicity(order)) of the roots.\r \n" ); document.write( "\n" ); document.write( "ex: g(x) = x^2 + 1. This has no solutions in real numbers, but by the fund thm of algebra, they have 2 solutions in complex numbers; namely x=i and x=-i, where i = sqrt(-1)\r \n" ); document.write( "\n" ); document.write( "ex: p(x) = x^2+2i+1. This has 1 solution in the complex numbers, x=i, but it has order 2, therefore it satisfies the fund thm of algebra\r \n" ); document.write( "\n" ); document.write( "can you now name how many solutions your functions will have in complex numbers? \n" ); document.write( " |
