Best ResponseYou've already chosen the best response.0I tried to bring it to the power by \[\frac{ 1 }{ 4 }x=1+(x+2)\] /is this correct?

Best ResponseYou've already chosen the best response.0see (a+b)^2 is NOT equal to a^2 + b^2 only. \[\large{(\frac{1X}{2})^2 = (1 + \sqrt{x2})^2 }\] \[\large{\frac{x^2}{4} = 1 + x2  2\sqrt{x2} }\]

Best ResponseYou've already chosen the best response.0Oh wait in your corrected question it is x+2 not x2 so it will be : \[\large{\frac{x} = 1+x2 2\sqrt{x+2}}\]

Best ResponseYou've already chosen the best response.0ok but I still don't understand how you broke it down to that. Can we go through it step by step?

Best ResponseYou've already chosen the best response.0Oh! Sorry I think I confused you, yes why not... so do you know the identity of (a+b)^2 = ?

Best ResponseYou've already chosen the best response.0Right! so in RHS (Right hand side) we have : 1 + sqrt{x+2} , correct?

Best ResponseYou've already chosen the best response.0left side of equation \[(\frac{ 1 }{ 2 }x)^2= \frac{ 1 }{ 4 }x\]. Correct?

Best ResponseYou've already chosen the best response.0right. That is the right hand side. What's next?

Best ResponseYou've already chosen the best response.0Yes , so square the right hand side ... that is : \[\large{( \sqrt{x+2}  1 )^2 }\] Can you square that?

Best ResponseYou've already chosen the best response.0no. Not 100% how to do it. That's what's messing me up.

Best ResponseYou've already chosen the best response.0add 1 to both sides and square both sides \[(\frac{ x }{ 2 } +1)^2 = x +2\]

Best ResponseYou've already chosen the best response.0\[ \frac{ x^2 }{4 } +x +1 = x+2\]
