When solving radical equations, the first thing that you want to do is isolate the radical.
00:05
Now there's more than one radical, so you have to choose which one it is.
00:09
However, both of them are already isolated on both sides, so your first step is to square both sides.

This gets us 10 plus 2c on the left, and then 4c plus 16 on the right.
00:20
So i'm going to move things around now.
00:22
So i'm going to subtract the 10 to the other side, and i'm going to subtract the 4c to the other side.
00:28
So what happens here is i'm getting variables on the left and numbers on the right.
00:32
2 minus 4 is negative 2c.
00:35
16 minus 10 is 6...
