Question

Find the co-ordinates of point on x-axis which are at distance of 17 units from the point (11 - 8)

Lesson : Distance formula
Formula : √(x2-x1)²+(y2-y1)²​

Answer 1

Answer:

Let the coordinates of point on x axis be (x,0 )

According to the question,

17=√(11-x)²+(-8-0)²

17=√121+x²-22x + 64

Squaring both sides, we get-

289=185+x²-22x

After factorization we will get answer
