错在哪里呢？

delta = b * b - 4 * a * c;
if (delta > 0)
{
x1 = (-b + sqrt(delta)) / (2 * a);
x2 = (-b - sqrt(delta)) / (2 * a);
printf("该一元二次方程有两个解,x1 = %f, x2 = %f\n", x1,x2);
}
else if (delta = 0)

x1 = (-b) / (2 * a);
x2 = x1;
printf("该一元二次方程有一个唯一解，x1 = x2 = %f"，x1);
}
else
{
printf("该一元二次方程无解");
}
return 0;
}
