0 votes 0 votes I THINK ANS IS NO... x4+7x3−13x2+11x =>x(x3+7x2-13x+11) so '0' is a root of the polynomial.... Again the coefficient of the given polynomial are real ... so if there are complex root ,they are two in number..., ami answered Apr 3, 2017 ami comment Share Follow See all 0 reply Please log in or register to add a comment.
