Answer:
4(x -  )² = 0
 )² = 0
Step-by-step explanation:
Given
4x² - 4x + 1 = 0
To complete the square the coefficient of the x² term must be 1
Factor out 4 from 4x² - 4x
= 4(x² - x) + 1 = 0
add/subtract ( half the coefficient of the x- term )² to x² - x
 4(x² + 2(-  )x +
 )x +  -
 -  ) + 1 = 0
 ) + 1 = 0
 4(x -  )² - 1 + 1 = 0
 )² - 1 + 1 = 0
4(x -  )² = 0
 )² = 0
 
        
                    
             
        
        
        
Answer:
Step-by-step explanation:
3 : 12
Both have table of 3 in common so
1 : 4 or 1/4
4 : 64
Both have table of 4 in common 
1 : 16 or 1/16
 
        
                    
             
        
        
        
2 in 83628 is the tenths and 208 is the hundreds
