Let \( \phi(x, y)=0 \) be the equation of a circle. If \( \phi(0, \lambda) \) \( =0 \) has equal roots \( \lambda=2,2 \) and \( \phi(\lambda, 0)=0 \) has roots
\( \mathrm{P} \)
\( \lambda=\frac{4}{5}, 5 \) then the centre of the circle is
(1) \( (2,29 / 10) \)
(2) \( (29 / 1,2) \)
(3) \( (-2,29 / 10) \)
(4) None of these
