sqrt(x+2)+4=x can anyone help?

Question

anonymous · Answer

$$\sqrt{x+2}+4=x$$

tkhunny · Answer

Subtract 4 to move everything except the square root to teh other side.  Then suare both sides.

Caution: You WILL lose something.  With the Square Root, x + 2 >= 0.  You no longer can see this after squaring.

yeah i know how to do that. but when i square does x-4 turn to (x-4)(x+4) and then we use the FOIL method?

tkhunny · Answer

Why would a SQUARE turn into something else?  $x+2 = (x-4)^{2} = (x-4)(x-4)$

anonymous · Answer

ok i went towards x-4 route and in the end i get$$\sqrt{8}+4=-6$$ and $$\sqrt{5}+4=3$$

tkhunny · Answer

That makes no sense.  Please include intermediate steps so we can see where you wandered off.
