咋就90分，错了第二个点，写着Wrong Answer.wrong answer Too long on line 1. 大佬帮帮忙

#include<bits/stdc++.h>
using namespace std;
double x1,x2,a,b,c;
int main(){
	cin>>a>>b>>c;
	if(b*b-4*a*c<0){
		cout<<"No answer!";
		return 0;
	}
	x1=(-b+sqrt(b*b-4*a*c))/(2*a);
	x2=(-b-sqrt(b*b-4*a*c))/(2*a);
	if(x1==x2){
		printf("x1=x2=%.5f",x1);
	}
	printf("x1=%.5f;x2=%.5f",min(x1,x2),max(x1,x2));
}
