The equation of the circle passing through (2a,0) and whose radical axis w.r. to the circlex^(2) +y^(2) = a^(2)isx = a//2 is

Answer»

CENTRE of C is `(-a,0)` and C PASSES through `(0,0)and (-a,-a)`
circle C is `x ^(2) + y ^(2) -2ax - 2ay =0`
centre of C ISW `(a,0) and ` C passes through (0,) and (a,a)
centre of C is `(0,-a)` and C passes through `(-a,-a) and (0,0)`
