代码：
clc;clear;
p1 = [537265,0,0,0,0,-7752905,7215640];
p2 = [537265,0,0,0,0,-6879917,6342652];
p3 = [537265,0,0,0,0,-6195671,5658406];
x1 = roots(p1);
x2 = roots(p2);
x3 = roots(p3);
x1

-1.5271 - 1.0207i
0.3522 + 1.6808i
0.3522 - 1.6808i

1.0000 + 0.0000i
x2 =
-1.4927 + 0.9970i
-1.4927 - 0.9970i
0.3419 + 1.6426i
0.3419 - 1.6426i
1.3016 + 0.0000i
1.0000 + 0.0000i
x3 =
-1.4631 + 0.9766i
-1.4631 - 0.9766i
0.3333 + 1.6097i
0.3333 - 1.6097i
1.2596 + 0.0000i
