What is the x-coordinate of the point on the x-axis that is equidistant from points A( -2, 0) and B(0,8)?

Since it is on the x axis, the point will be of the from  (x,0 )   

  Use the distance formula :for point 1 and point 2 and equate them

 

(-2 - x )^2 + 0^2  = x^2 + (8)^2

x^2 + 4x + 4 = x^2 + 64

4x -60 = 0

x = 15
