HI GUYS ✌️✌️✌️✌️
GOOD EVENING ️✋
HERE IS THE QUESTION:
FIND THE POINT ON THE X-AXIS WHICH IS EQUIDISTANT FROM THE POINTS (2,-5) AND (-2,9).....‼️‼️‼️‼️
WAITING FOR YOUR ANSWER ♥️♥️♥️♥️​

Answer 1

let the point on the x axis be P( x,0)

Given:

A(2, -5) and B(-2, 9) are equidistant from P

That is PA = PB

Hence PA2 = PB2 -------> (1)

Distance between two points is √[(x2 - x1)2 + (y2 - y1)2]

PA = √[(2 - x)2 + (-5 - 0)2]

PA2 = 4 - 4x +x2 + 25 = x2 - 4x + 29

Similarly, PB2 = x2 + 4x + 85

Equation (1) becomes

x2 - 4x + 29 = x2 + 4x + 85

- 8x = 56

x = -7

Hence the point on x-axis is (-7, 0)
