All right, so first I'll try when I add the radical. So I'm going to get 200, 200 plus the square root of 40,000. I could have just written that, I could have just written that as 200 squared, but that's fine, 40,000 minus four times 12, times 600, times 600. And I get 305, which I then need to divide by 24. Which I'll divide by 24. And I get 12.74. So one of my possible x's.
