I assume the question was

√(x + 14) + 2 = x
We can move the 2 over to the other side, and then square it so that:

x + 14 = (x - 2) ^(2)
Simplifying, we get:

x + 14 = {x}^(2) - 4x + 4
So

{x}^(2) - 5x - 10 = 0
However, this means that using the quadratic formula,

x = (5 + √(65) )/(2)
Or

x = (5 - √(65) )/(2)
Hope this helped in some way, I may have made a mistake somewhere, so you should probably double check.
