Two circles with equal radii are externally tangent
at a point on the parabola y = x2. One of the circles
is also tangent to the x-axis while the other is also
tangent to the y-axis. Find the radius of both circles.

As noted by Charlie:


What's wanted but not explicitly stated is that the circles should also be tangent to the parabola.
