Best ResponseYou've already chosen the best response.0\[p(x)=x^{13}7x^38\] only once sign changes so there is a positive root or no positive root \[p(x)=x^{13}7x^38\] there is no sign changes so it has no negative root we know that x=1 is a root and it is positive so all the rest roots are complex..
