Question

Find those points on the x-axis, euch of which is at a distance of 5 units from the point (5,-3)​

Answer 1

Answer:

Let the coordinates of the point be x,y

Since the point is on x axis, y= 0

using distance formula

√{(x-5)^2+(-3-0)^2}= 5

√{(x-5)^2+9}=5

By squaring both sides

x^2-10x+25+9=25

x^2-10x+9=0

(x-9)(x-1)=0

So coordinates are 9,0 and 1,0
