Step 10.3.1.9

Multiply $2$ by $- 21$ .

$\frac{16 m^{4} + 182 m^{3} + 581 m^{2} + 416 m - 259 - 4 m^{4} - 42 m^{3} - (35 m^{2}) \cdot 2 - (- 37 m) \cdot 2 - 1 \cdot 45 \cdot 2}{{(2 m + 7)}^{2}}$

Step 10.3.1.10

Multiply $35$ by $- 1$ .

$\frac{16 m^{4} + 182 m^{3} + 581 m^{2} + 416 m - 259 - 4 m^{4} - 42 m^{3} - 35 m^{2} \cdot 2 - (- 37 m) \cdot 2 - 1 \cdot 45 \cdot 2}{{(2 m + 7)}^{2}}$

Step 10.3.1.11

Multiply $2$ by $- 35$ .

$\frac{16 m^{4} + 182 m^{3} + 581 m^{2} + 416 m - 259 - 4 m^{4} - 42 m^{3} - 70 m^{2} - (- 37 m) \cdot 2 - 1 \cdot 45 \cdot 2}{{(2 m + 7)}^{2}}$

Step 10.3.1.12

Multiply $- 37$ by $- 1$ .

$\frac{16 m^{4} + 182 m^{3} + 581 m^{2} + 416 m - 259 - 4 m^{4} - 42 m^{3} - 70 m^{2} + 37 m \cdot 2 - 1 \cdot 45 \cdot 2}{{(2 m + 7)}^{2}}$

Step 10.3.1.13

Multiply $2$ by $37$ .

$\frac{16 m^{4} + 182 m^{3} + 581 m^{2} + 416 m - 259 - 4 m^{4} - 42 m^{3} - 70 m^{2} + 74 m - 1 \cdot 45 \cdot 2}{{(2 m + 7)}^{2}}$
