If the sum of the squares of the distances of the point (x, y) from the points (a, 0) and (-a,0) is `2b^(2)`, then which one of the following is correct ?

Options

A. `x^(2) + a^(2) = b^(2) + y^(2)`
B. `x^(2) + a^(2) = 2b^(2) - y^(2)`
C. `x^(2) - a^(2) = b^(2) + y^(2)`
D. `x^(2) + a^(2) = b^(2) - y = 2`

Answer

D
