`S_(1)=x^(2)+y^(2)+4y-1=0`,
`S_(2)=x^(2)+y^(2)+6x+y+8=0`,
`S_(3)=x^(2)+y^(2)-4x-4y-37=0`
touches the other two. Let `P_(1), P_(2), P_(3)` be the points of contact of `S_(1) and S_(2), S_(2) and S_(3), S_(3) and S_(1)` respectively and `C_(1), C_(2), C_(3)` be the centres of `S_(1), S_(2), S_(3)` respectively.
