An ellipse having foci `(3,1)` and `(1, 1)` passes through the point `(1, 3)` has the eccentricity

An ellipse having foci at (3,1) and (1,1) passes through the point (1,3) .Its eccentricity is: (A) sqrt(2)-1 (B) sqrt(3)-1 (C) (1)/(2)(sqrt(2)-1) (D) (1)/(2)(sqrt(3)-1)

An ellipse has foci (4, 2), (2, 2) and it passes through the point P (2, 4). The eccentricity of the ellipse is

An ellipse having foci at (3, 3) and (-4,4) and passing through the origin has eccentricity equal to (a) 3/7 (b) 2/7 (c) 5/7 (d) 3/5

An ellipse having foci at (3, 3) and (-4,4) and passing through the origin has eccentricity equal to 3/7 (b) 2/7 (c) 5/7 (d) 3/5

An ellipse having foci at (3, 3) and (-4,4) and passing through the origin has eccentricity equal to (a) 3/7 (b) 2/7 (c) 5/7 (d) 3/5

An ellipse having foci at (3, 3) and (-4,4) and passing through the origin has eccentricity equal to (a) 3/7 (b) 2/7 (c) 5/7 (d) 3/5

An ellipse having foci at (3, 3) and (-4,4) and passing through the origin has eccentricity equal to (a) 3/7 (b) 2/7 (c) 5/7 (d) 3/5

An ellipse having foci at (3,3) and (-4,4) and passing through the origin has eccentricity equal to (3)/(7) (b) (2)/(7)(c)(5)/(7)(d)(3)/(5)

An ellipse with foci (-1,1) and (1,1) passes through (0,0) .Then its equation is
