A certain circle can be represented by the following equation. x^2+y^2+18x+14y+105=0 What is the center of the circle? What is the radius of the circle?

See below.

Step-by-step explanation:

Recall the equation for a circle:

, where (h,k) is the center and r is the radius.

We need to turn the given equation into the above format. We do this by completing the square.

First, group them:

For the first section, complete the square for :

Do the same for the second:

All together:

The center is (-9,-7).

The radius is

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )
