Answer:
4(x -
)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 +
-
) + 1 = 0
4(x -
)² - 1 + 1 = 0
4(x -
)² = 0
Answer:
9
Step-by-step explanation:
Using the rule of radicals
×
⇔ 
Simplify the radicals

= 
=
× 
= 2

= 
=
× 
= 3
Then
3
+ 
= 3(2
) + 3
= 6
+ 3
= 9
