Solution :

Given points : A (2,-5) and B (-2,9)

ㅤㅤㅤㅤㅤㅤ

Let points be P (x,0)

ㅤㅤㅤㅤㅤㅤ

So, AP = BP also AP² = BP²

ㅤㅤㅤㅤㅤㅤ

(x-2)² + (0+5)² = (x + 2)² + (0-9)²

ㅤㅤㅤㅤㅤㅤ

↦ x² + 4 - 4x + 25 = x² + 4x + 4x + 81

ㅤㅤㅤㅤㅤㅤ

↦ x² + 29 - 4x = x² + 85 + 4x

ㅤㅤㅤㅤㅤㅤ

↦ -4x - 4x = 85 - 29

ㅤㅤㅤㅤㅤㅤ

↦ -8x = 56

ㅤㅤㅤㅤㅤㅤ

↦ x = -7

ㅤㅤㅤㅤㅤㅤ

_________________________

So, correct opt is (-7,0)
