A circle has the equation 2x2+12x+2y2−16y−150=0.
What are the coordinates of the center, and what is the length of the radius?

The coordinates of the center are (−3,4), and the length of the radius is 10 units.

The coordinates of the center are (3,−4), and the length of the radius is 10 units.

The coordinates of the center are (6,−8), and the length of the radius is 10 units.

The coordinates of the center are (−6,8), and the length of the radius is 10 units.

hello :

2x²+12x+2y²−16y−150=0

divide by 2 : (x²+6x)+(y²-8y)-75 =0

(x²+6x+9)-9+(y²-8y+16)-16-75 =0

(x+3)²+(y-4)² =10²

The coordinates of the center are (−3,4), and the length of the radius is 10 units.
