Question

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

Answer 1

\[\sqrt{x+2}+4=x\]

Answer 2

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.

Answer 3

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?

Answer 4

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

Answer 5

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

Answer 6

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

Answer 7

uh whatever i just checked my work and i fixed something and now im figuring out the right answer
