Two equal circles with their centres as x and y axis will possess the radical axis in the following form

The circle with centre (4,-1) and touching x-axis is

The circle with centre (4,-1) and touching x-axis is

If the radical axis of two circles with centres A and B bisects AB then their radii are in the ratio

Two circles of equal radius a cut orthogonally. If their centres are (2,3) and (5,6), then radical axis of these circles passes through the point

Two circles of equal radius a cut orthogonally . If their centres are (2,3) and (5,6) then radical axis of these circles passes through the point

If centre lies on x axis then equation of circle is of the form

If centre lies on x axis then equation of circle is of the form

If centre lies on x axis then equation of circle is of the form

The circle with centre (2,3) touching x-axis has the radius equal to
