The circles whose equations are x^(2)+y^...

The circles whose equations are` x^(2)+y^(2)+10x-2y+22`=0 and `x^(2)+y^(2)+2x-8y+8=0 `touch each other. The circle which touch both circles at, the point of contact and passing through (0,0) is,
1) `9(x^(2)+y^(2))-15x-20y=0`
2) `5(x^(2)+y^(2))-18x-80y=0 `
3) `7(x^(2)+y^(2))-18x-80y=0` 4)` x^(2)+y^(2)-9x-40y=0]`
