But 2 or -1 doesn't show :(
square both sides and then rearrange so it gives x^2-x-2=0 then you factorise to give (x-2)(x+1) hence x is 2 or -1

Coconutshake, if you square:\[\sqrt{x}+14-12=x\],\[\sqrt{x}+2=x\]wouldnt' you get \[x+4=x^{2}\] Therefore the equation\[x^{2}-x-4=0\]
ekk that should be \[x^{2}-4x+4=0 \]
Therefore the answer is 2.
Therefore your answer is wrong
x = -10 and x = -13 is the correct answer
