A tangent to the circle x^(2)+y^(2)=4 meets the coordinate axes at P and Q. The locus of midpoint of PQ is

Two tangents are drawn from a point P to the circle x^(2)+y^(2)+2gx+2fy+c=0 . If these tangents cut the coordinate axes in concyclic points show hat the locus of P is (x+y+g+f)(x-y+g-f)=0

Two tangents are drawn from a point P to the circle x^(2)+y^(2)+2gx+2fy+c=0 . If these tangents cut the coordinate axes in concyclic points show hat the locus of P is (x+y+g+f)(x-y+g-f)=0

The circles x^(2) +y^(2) + 2ax +c =0 and x^(2) +y^(2) +2bx +c =0 have no common tangent if
