1.

 

2x^2  -  4x   +   16  = 0      divide through by 2

 

x^2  -  2x  +   8   =  0      complete the square on  x

 

x^2 -  2x   +  1    =  - 8  +  1

 

(x - 1)^2  =   - 7

 

x  - 1   =   ±√-7

 

x  =   ± i√7    +  1

 

The second answer is correct

 

2. 

 

Here are the answers that go into each box 

 

x^4  +  2x^2y^2  + y^4

 

x^4  +  4x^2y^2

 

x^2 (x^2 + 4y^2)
