Answer 1

Answer:

To complete the square, you always want to add $(\frac{a}{2} )^{2}$, where a is the coefficient of x.

In this case, the coefficient of x is -1.

Thus,

$y=x^2-x+1$

$y=x^2-x+(\frac{-1}{2})^2 +1-(\frac{-1}{2})^2$

$y=(x-\frac{1}{2})^2+1-\frac{1}{4}$

$y=(x-\frac{1}{2})^2+\frac{3}{4}$
