Question

CO-ORDINATE GEOMETRY
EXAMPLE 5.

Can anybody explain why square root isn't used.

since, it's there in distance formula.

Answer 1

SOLUTION.......


Any point on y-axis,
y =0, thèrefore point P = ( x , 0 )
Now,
Point P is equidistant from A and B
So,

PA = PB
$\sqrt{ {(6 - x)}^{2} + {(5 - 0)}^{2} } = \sqrt{ { ( - 4 - x)}^{2} + {(3 - 0)}^{2} }$

To solve this,
we get,

x = 9/5.

Therefore, Point P = ( 9/5, 0 ).
