    设[img=34x25]18034355a39e05a.png[/img]是实数域上多项式,则错误的结论应该是
    未知类型:{'options': ['若[img=34x25]18034355ac12ca2.png[/img]可约,则每个不可约因子的次数不超过2', '若[img=34x25]18034355ac12ca2.png[/img]的系数全是正实数,则它没有正实数根', '若[img=34x25]18034355ac12ca2.png[/img]可约,则它必有实数根', '若[img=34x25]18034355ac12ca2.png[/img]的次数是奇数,则它必有实数根'], 'type': 102}
