Question

Find the constant sum for an ellipse with foci F1 (3, 0), F2 (24, 0) and the point on the ellipse (9, 8).

Answer 1

you have the points \(F_1(3,0)\) and \(F_1(24,0)\) and \(P(9,8)\) then by the definition of an ellipse u gotta have
\[ \large d(F_1,P)+d(F_2,P)=\text{constant} \]

Answer 2

\(d\) is the distance
