00:03 In order to simplify using the square root property, we have to isolate our quadratic part of the problem.
00:11 So in this case, that's the n -4 squared.
00:15 So we're going to isolate that by subtracting three from both sides.
00:20 So that leaves me with n -4 square equal to 12.
00:27 And now i'm going to apply the square root property.
00:30 We're going to take the square root of the left side, as well as the square root of the right set.
00:35 And when i take the square root of a number, i have to make sure to include my plus or minus...
