Given,
The points are (2,-5) and (-2,9).
To find,
The point on the x-axis which is equidistant from the two given points.
Solution,
Now,the point is on x-axis,so the value 'y' of the given point will be zero.
Let,the value of the 'x' value of the given point = x
[Assume,x as a variable to do the further mathematical calculations.]
So,the point is = (x,0)
As mentioned in the question,the two points are equidistant from (x,0).
So,
Distance between (x,0) and (2,-5)
= ✓(x-2)²+(0+5)²
Distance between (x,0) and (-2,9).
=✓(x+2)²+(0-9)²
Now,the points are equidistant.
So,
✓(x-2)²+(0+5)² = ✓(x+2)²+(0-9)²
(x-2)²+(0+5)² = (x+2)²+(0-9)²
x²-4x+4+25 = x²+4x+4+81
x²-4x-x²-4x = 4+81-4-25
-8x = 56
x = -7
Hence,the point on x-axis is (-7,0).
