This question will recall about the equation of the sphere with the center equal to the x0, y -zo, z, z, and the radius equal to r.
00:14
Then the equation will be x minus x0 square, plus y minus y z square, plus z minus z zero square, equal to r square.
00:28
In this question, we're given the equation of the x square plus y square plus z squared minus y equal to 0.
00:38
Here, the first time we need to group the x into 1, so have only 1 x, y into 1 group, so minus y, and z into another group, equal to 0.

The next step, we'll do the completing the square, so we can write this now into the x minus 0 square...
