Answer 1

Answer:

$\Large \boxed{\mathrm{\bold{A.} \ \frac{1}{4} }}$

Step-by-step explanation:

$x^2 +x$

The expression is in the form ax² + bx.

$a=1 \\ \\ b=1$

Find the discriminant and add to the expression.

$\displaystyle (\frac{b}{2} )^2 =(\frac{1}{2} )^2 =\frac{1}{4}$

Adding $\frac{1}{4}$ to the expression.

$\displaystyle x^2 +x+\frac{1}{4}$
