Answer:
The point on x-axis is (x,0)
(x-2)^2 +25=(x+2)^2 +49
-8x=24
x=-3
Therefore the point on the x-axis is (-3,0)

GIVEN:-
Two points are A(2,-5) and B(-2,7)
TO FIND:-
A point on x axis that is equidistant from the given two points
EXPLANATION:-
As the point is on x-axis ,y-coordinate is 0
let the point that is equidistant from A and B be P(x,0)
Finding PA:-
Finding PB:-
According to the given information
PA=PB
squaring on both sides
PA²=PB²
expanding using
(a+b)²=a²+b²+2ab
So the point is (-3,0)
