x^2 + 16x + 64 + y^2 - 24y + 144 = -159 + 64 + 144
(x +8)^2 + (y - 12)^2 = 49
Center: (-8,12)

Answer:

Explanation:

alright lets get started.

We have given the equation of the circle as


x^2+y^2+16x-24y+159=0

adding and subtracting 64 from above equation


x^2+y^2+16x-24y+159+64-64=0


x^2+16x+64+y^2-24y+95=0


(x+8)^2+y^2-24y+95=0

adding and subtracting 144 from above equation


(x+8)^2+y^2-24y+95+144-144=0


(x+8)^2+(y-12)^2-49=0


(x+8)^2+(y-12)^2=49

Hence, this is the standard form of circle equation,

So, the center of the circle will be (-8,12). answer

Hope it will help.
