Step 2.1

Apply the distributive property.

$- 5 x^{2} - 2 x - (7 x) - 1 \cdot 2$

Step 2.2

Multiply $7$ by $- 1$ .

$- 5 x^{2} - 2 x - 7 x - 1 \cdot 2$

Step 2.3

Multiply $- 1$ by $2$ .

$- 5 x^{2} - 2 x - 7 x - 2$

$- 5 x^{2} - 2 x - 7 x - 2$

Step 3

Subtract $7 x$ from $- 2 x$ .

$- 5 x^{2} - 9 x - 2$
