Step 1.1

Apply the distributive property.

$x (x - 5) - 6 (x - 5)$

Step 1.2

Apply the distributive property.

$x \cdot x + x \cdot - 5 - 6 (x - 5)$

Step 1.3

Apply the distributive property.

$x \cdot x + x \cdot - 5 - 6 x - 6 \cdot - 5$

$x \cdot x + x \cdot - 5 - 6 x - 6 \cdot - 5$

Step 2.1.1

Multiply $x$ by $x$ .

$x^{2} + x \cdot - 5 - 6 x - 6 \cdot - 5$

Step 2.1.2

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

$x^{2} - 5 \cdot x - 6 x - 6 \cdot - 5$

Step 2.1.3

Multiply $- 6$ by $- 5$ .

$x^{2} - 5 x - 6 x + 30$

$x^{2} - 5 x - 6 x + 30$

Step 2.2

Subtract $6 x$ from $- 5 x$ .

$x^{2} - 11 x + 30$

$x^{2} - 11 x + 30$

$[\begin{array}{c} x^{2} & \frac{1}{2} \\ \sqrt{π} & \int x d x \end{array}]$
