Answer:
x = 10
Step-by-step explanation:
x = 4 + (4x-4) ^ (1/2)
 First, we rewrite the expression:
 x = 4 + (4x-4) ^ (1/2)
 x = 2 (2+ (x-1) ^ (1/2))
 x = 4 + 2 (x-1) ^ (1/2)
 From here we get a solution for x = 10
 To check it we substitute x = 10 in the expression:
 10 = 4 + 2 (10-1) ^ (1/2)
 10 = 4 + 2 (9) ^ (1/2)
 10 = 4 + 2 (3)
 10 = 4 + 6
 10 = 10
 Answer:
 The solution is:
 x = 10
 
        
                    
             
        
        
        
Answer:B
Step-by-step explanation:
Honestly when I did the math I got closest to b so I think it's B hope his helps
 
        
             
        
        
        
After the expression is simplified as much as possible, x is raised to the exponent 2

Answer:
   1 +i√3.5
Step-by-step explanation:
In vertex form, the equation is ...
   2(x² -2x +1) +7 = 0
   2(x -1)² +7 = 0
Then the solutions are ...
   (x -1)² = -7/2
   x = 1 ±i√3.5
One solution is 1+i√3.5.
