A point on the curve y=x2 has coordinates (x,x2).
Using the distance formula:
Distance from (x,x2) to (−1,0): (x+1)2+(x2)2
Distance from (x,x2) to (5,0): (x−5)2+(x2)2
Since the point is equidistant from both points:
(x+1)2+(x2)2=(x−5)2+(x2)2
(x+1)2+(x2)2=(x−5)2+(x2)2
The (x2)2 terms cancel:
(x+1)2=(x−5)2
x2+2x+1=x2−10x+25
The x2 terms cancel:
2x+1=−10x+25
12x=24
x=2
Since the point is on y=x2:
y=(2)2
y=4
Therefore, the point (2,4) on the curve y=x2 is equidistant from (−1,0) and (5,0).
