Rewrite the equation by completing the square.

4(x - )² = 0

Step-by-step explanation:

Given

4x² - 4x + 1 = 0 ( factor out 4 from the first 2 terms )

4(x² - x) + 1 = 0

To complete the square

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

the answer is a.

135 and 80
