The coordinates (2, 3) and (1, 5) are the foci of an ellipse which passes through the origin. Then the equation of the (a)tangent at the origin is `(3sqrt(2)-5)x+(1-2sqrt(2))y=0` (b)tangent at the origin is `(3sqrt(2)+5)x+(1+2sqrt(2)y)=0` (c)tangent at the origin is `(3sqrt(2)+5)x-(2sqrt(2+1))y=0` (d)tangent at the origin is `(3sqrt(2)-5)-y(1-2sqrt(2))=0`
