 x = 4

Step-by-step explanation:

= + 2

RESTRICTIONS: x + 12 ≥ 0 and x ≥ 0  →  x ≥ 0  (because square roots cannot be negative)

=

  x + 12 = x + 4 + 4

  -x   -4 -x             -4  

        8  =      4

     ÷4       ÷4      

        2  =        

       (2)² =    

  +/-  4  =  x

Solutions: x = 4, x = -4    however, x = -4 is restricted so not valid
