144 minus 60 is 84. All of that over six. So x could be equal to 12 plus the square root of 84 over six or x could be equal to 12 minus the square root of 84 over six. So let's figure out what these two are. And I'll use the calculator. I'll use the calculator for this one. So I get, let's see, 12 plus the square root of 84 divided by six gives me 3.5, I'll just say 3.53.
