Step 2.1.1

Multiply $x$ by $x$ .

$x^{2} + x (- \frac{5}{6}) + \frac{1}{6} x + \frac{1}{6} (- \frac{5}{6})$

Step 2.1.2

Combine $x$ and $\frac{5}{6}$ .

$x^{2} - \frac{x \cdot 5}{6} + \frac{1}{6} x + \frac{1}{6} (- \frac{5}{6})$

Step 2.1.3

Move $5$ to the left of $x$ .

$x^{2} - \frac{5 \cdot x}{6} + \frac{1}{6} x + \frac{1}{6} (- \frac{5}{6})$

Step 2.1.4

Combine $\frac{1}{6}$ and $x$ .

$x^{2} - \frac{5 x}{6} + \frac{x}{6} + \frac{1}{6} (- \frac{5}{6})$
