(under a radical) -x+6 + (under a different radical) x-5 = 1
----
sqrt(-x+6) + sqrt(x-5) = 1
---
Square both sides to get:
(-x+6) + (x-5) + 2sqrt(-x^2+11x-30) = 1
---------
2sqrt(-x^2+11x-30) = 0
---
sqrt(-x^2+11x-30) = 0
---
-x^2+11x-30 = 0
---
x^2-11x+30 = 0
---
Factor:
(x-6)(x+5) = 0
-----
Acceptable answer:
x = 6
