Step 1.2.1

Multiply $3$ by $- 9$ .

$2 a - 27 a^{2} - 9 (4 a) - 9 \cdot - 4$

Step 1.2.2

Multiply $4$ by $- 9$ .

$2 a - 27 a^{2} - 36 a - 9 \cdot - 4$

Step 1.2.3

Multiply $- 9$ by $- 4$ .

$2 a - 27 a^{2} - 36 a + 36$

$2 a - 27 a^{2} - 36 a + 36$

$2 a - 27 a^{2} - 36 a + 36$

Step 2

Subtract $36 a$ from $2 a$ .

$- 27 a^{2} - 34 a + 36$
