Step 1.1

Apply the distributive property.

$- 5 (3 c) - 5 \cdot - 9 - 9 c - 7 c^{2} + 5$

Step 1.2

Multiply $3$ by $- 5$ .

$- 15 c - 5 \cdot - 9 - 9 c - 7 c^{2} + 5$

Step 1.3

Multiply $- 5$ by $- 9$ .

$- 15 c + 45 - 9 c - 7 c^{2} + 5$

$- 15 c + 45 - 9 c - 7 c^{2} + 5$

Step 2

Simplify by adding terms.

Step 2.2.1

Add $45$ and $5$ .

$- 24 c - 7 c^{2} + 50$

Step 2.2.2

Reorder $- 24 c$ and $- 7 c^{2}$ .

$- 7 c^{2} - 24 c + 50$

$- 7 c^{2} - 24 c + 50$

$- 7 c^{2} - 24 c + 50$
