The equation of locus of a point which moves so that the sum of the square of its distance from the coordinate axes is 15 is
Locus of the centre of the circle which touches the two circle x2+y2+8x–9=0 and x2+y2–8x+7=0 externally, is
A point moves in such a way that the sum of square of its distance from the points A(2, 0) and B(-2, 0) is always
equal to the square of the distance between A and B. The locus of the point is
