Heyy...
Your points for the coordinate will be (x,0)
Distance= 2 root 5
You will get 2 values for x..
X=5
X=9

Let point on x axis be A.
So coordinates of A ( x, 0 )
Another point be B ( 7,-4 )
Distance AB = 2√5 units.
Now,
Distance AB = √(x2 - x1 )² + (y2 - y1)²
√(7 - x )² + (-4 - 0)² = 2√5
49 - 14x + x² + 16 = (2√5)²
x² - 14x + 65 = 20
x² - 14x + 65 -20 = 0
x² - 14x + 45 = 0
x² - 5x - 9x + 45 = 0
x ( x - 5 ) - 9 ( x - 5 ) = 0
( x - 5 ) ( x - 9 ) = 0
Case I,
x - 5 = 0
x = 5
Case II,
x - 9 = 0
x = 9
Hope it may help you!!!!!
