$\frac{6 q^{13} + 24 q^{6} + 7 q^{13} + 42 q^{7} - 2 q^{7} (q^{6} + 6) - 8 (q^{6} + 6)}{2 q^{3}}$

Step 4.12.7.1.14.2

Apply the distributive property.

$\frac{6 q^{13} + 24 q^{6} + 7 q^{13} + 42 q^{7} - 2 q^{7} q^{6} - 2 q^{7} \cdot 6 - 8 (q^{6} + 6)}{2 q^{3}}$

Step 4.12.7.1.14.3

Apply the distributive property.

$\frac{6 q^{13} + 24 q^{6} + 7 q^{13} + 42 q^{7} - 2 q^{7} q^{6} - 2 q^{7} \cdot 6 - 8 q^{6} - 8 \cdot 6}{2 q^{3}}$

Step 4.12.7.1.15.1.1

Move $q^{6}$ .

$\frac{6 q^{13} + 24 q^{6} + 7 q^{13} + 42 q^{7} - 2 (q^{6} q^{7}) - 2 q^{7} \cdot 6 - 8 q^{6} - 8 \cdot 6}{2 q^{3}}$

Step 4.12.7.1.15.1.2

Use the power rule $a^{m} a^{n} = a^{m + n}$ to combine exponents.

$\frac{6 q^{13} + 24 q^{6} + 7 q^{13} + 42 q^{7} - 2 q^{6 + 7} - 2 q^{7} \cdot 6 - 8 q^{6} - 8 \cdot 6}{2 q^{3}}$

Step 4.12.7.1.15.1.3

Add $6$ and $7$ .

$\frac{6 q^{13} + 24 q^{6} + 7 q^{13} + 42 q^{7} - 2 q^{13} - 2 q^{7} \cdot 6 - 8 q^{6} - 8 \cdot 6}{2 q^{3}}$

Step 4.12.7.1.15.2

Multiply $6$ by $- 2$ .

$\frac{6 q^{13} + 24 q^{6} + 7 q^{13} + 42 q^{7} - 2 q^{13} - 12 q^{7} - 8 q^{6} - 8 \cdot 6}{2 q^{3}}$

Step 4.12.7.1.15.3

Multiply $- 8$ by $6$ .

$\frac{6 q^{13} + 24 q^{6} + 7 q^{13} + 42 q^{7} - 2 q^{13} - 12 q^{7} - 8 q^{6} - 48}{2 q^{3}}$

Step 4.12.7.2

Add $6 q^{13}$ and $7 q^{13}$ .

$\frac{13 q^{13} + 24 q^{6} + 42 q^{7} - 2 q^{13} - 12 q^{7} - 8 q^{6} - 48}{2 q^{3}}$

Step 4.12.7.3

Subtract $2 q^{13}$ from $13 q^{13}$ .

$\frac{11 q^{13} + 24 q^{6} + 42 q^{7} - 12 q^{7} - 8 q^{6} - 48}{2 q^{3}}$

Step 4.12.7.4

Subtract $8 q^{6}$ from $24 q^{6}$ .

$\frac{11 q^{13} + 42 q^{7} - 12 q^{7} + 16 q^{6} - 48}{2 q^{3}}$

Step 4.12.7.5

Subtract $12 q^{7}$ from $42 q^{7}$ .

$\frac{11 q^{13} + 30 q^{7} + 16 q^{6} - 48}{2 q^{3}}$

Step 5

Reform the equation by setting the left side equal to the right side.

$p' = \frac{11 q^{13} + 30 q^{7} + 16 q^{6} - 48}{2 q^{3}}$

Step 6

Replace $p'$ with $\frac{d p}{d q}$ .

$\frac{d p}{d q} = \frac{11 q^{13} + 30 q^{7} + 16 q^{6} - 48}{2 q^{3}}$
