$x^{2} - 11 x + n$

Step 1

Move $- 11 x$ .

$x^{2} + n - 11 x$

Step 2

To find the $c$ value $c = {(\frac{b}{2})}^{2}$ , divide the coefficient of $x$ by $2$ and square the result.

Step 2.1.1

Apply the product rule to $- \frac{11}{2}$ .

${(- 1)}^{2} {(\frac{11}{2})}^{2}$

Step 2.1.2

Apply the product rule to $\frac{11}{2}$ .

${(- 1)}^{2} \frac{11^{2}}{2^{2}}$

Step 2.2

Raise $- 1$ to the power of $2$ .

$1 \frac{11^{2}}{2^{2}}$

Step 2.3

Multiply $\frac{11^{2}}{2^{2}}$ by $1$ .

$\frac{11^{2}}{2^{2}}$

Step 2.4

Raise $11$ to the power of $2$ .

$\frac{121}{2^{2}}$

Step 2.5

Raise $2$ to the power of $2$ .

$\frac{121}{4}$
