Đường tròn  (C)\left(C\right)  có tâm  I(2;1)I\left(-2;1\right)  và tiếp xúc với đường thẳng  d: 3x4y+5=0d:\ 3x-4y+5=0  có phương trình là

 (x+2)2+(y1)2=1\left(x+2\right)^2+\left(y-1\right)^2=1  

 (x+2)2+(y1)2=125\left(x+2\right)^2+\left(y-1\right)^2=\frac{1}{25}  

 (x2)2+(y+1)2=1\left(x-2\right)^2+\left(y+1\right)^2=1  

 (x+2)2+(y1)2=4\left(x+2\right)^2+\left(y-1\right)^2=4
