We need to find the center and the radius and then graph the given circle.
00:04
So we're going to rearrange this.
00:07
So we're going to have 3x squared plus 24x.
00:13
Going to leave some space plus 3y squared minus 18y leaves some space equals.
00:19
Move the 24 over so that's minus 24.
00:22
So we're going to pull out a common 3.
00:25
So this is x squared plus 8x.
00:28
So we're going to take that middle number, 8 divided by 2, and square it.
00:34
And so that's plus 16.
00:37
But we're really adding 48.
00:41
So over here it's going to be minus 24 plus 48.
00:47
Then we're going to do the same thing with the y.
00:50
Pull out a 3.
00:51
So we have y squared minus 6...
