JEE Main 2026 Mathematics question
The number of values of z ∈ ℂ, satisfying the equations |z − (4 + 8i)| = √10 and |z − (3 + 5i)| + |z − (5 + 11i)| = 4√5, is:
Answer: (B)
Solution
The second equation is an ellipse with foci (3,5) and (5,11): 2c=2√10, 2a=4√5, so a²=20, c²=10, b²=10, with centre (4,8). The first
