Let us consider (a, 0) be the point on the x-axis that is equidistant from the point (7, 6) and (3, 4).
So,
\( \sqrt{(7 - a)^2 + (6-0)^2}\)
= \( \sqrt{(3 - a)^2 + (4-0)^2}\)
\( \sqrt{49 + a^2-14a+36 }\)
= \( \sqrt{9 + a^2-6a+16 }\)
\( \sqrt{ a^2-14a+85 }\)
= \( \sqrt{ a^2-6a+25 }\)
Now, let us square on both the sides we get,
a2 – 14a + 85 = a2 – 6a + 25
-8a = -60
a = \( \dfrac{60}{8}\)
= \( \dfrac{15}{2}\)
The required point is (\( \dfrac{15}{2}\), 0)
