Answer :

Let the point be (x, 0) on x–axis which is equidistant from (2, –5) and (–2, 9).

Using Distance Formula and according to given conditions we have:

\(\sqrt{(x - 2)^2 + ( 0 - (-5))^2} \)

\( = \sqrt{ (x - (-2))^2 + ( 0 - 9)^2}\)

=>\(\sqrt {x^2 + 4 - 4x + 25} \)

\( = \sqrt {x^2 + 4 + 4x + 81}\)

Squaring both sides, we get

\(\Rightarrow x^2 + 4 - 4x + 25 = x^2 + 4 + 4x + 81\)

\(\Rightarrow-4x + 29 = 4x + 85\)

\( \Rightarrow 8x = -56\)

\( \Rightarrow x = -7\)

Therefore, point on the x–axis which is equidistant from (2, –5) and (–2, 9) is (–7, 0)

- In a classroom, 4 friends are seated at the points A (3, 4), B (6, 7), C (9, 4) and D (6, 1). Champa and Chameli walk into the class and after observing for a few minutes Champa asks Chameli. “Don’t you think ABCD is a square?”Chameli disagrees. Using distance formula, find which of them is correct.
