SOLUTION: 6 - radical x+2 =x+2

 

Hi,

6 - radical x+2 =x+2

Let s =  ⇒ 

 6 -s = s^2

 s^2 + s - 6 = 0  Factor to find solutions

(s+3)(s-2) = 0,  s = -3 (extraneous)  0r s = 2   

 s =   

   2=   x = 2

0r s^2 = 4 = x+2 ,  x = 2

CHECKING our answer***

 6 - 2 = 4

Wish You the Best in your Studies.
