We need to complete the square in order to find the equation of the circle in standard form.
00:04
Identify the center and the radius.
00:06
And if we can't, we need to explain y.
00:12
So we're going to move.
00:13
We have x squared plus 5x.
00:16
Move the leaves in space.
00:18
Then we have plus y squared minus y.
00:20
Leave some space.
00:21
Move the one over.
00:23
We take the middle term, which is 5 divided by 2.
00:27
Square it.
00:28
So that's plus 25 over 4.
00:30
So that gets added to both sides.
00:33
Then we take the minus 1 divided by 2 and square it...
