$\frac{1}{4 \cdot 5^{\frac{1}{2}}} \cdot \frac{{(x^{3} - 5 x)}^{\frac{3}{2}} (\frac{d}{d x} [3 x^{4}] + \frac{d}{d x} [- 30 x^{2}] + \frac{d}{d x} [- 25]) - (3 x^{4} - 30 x^{2} - 25) \frac{d}{d x} [{(x^{3} - 5 x)}^{\frac{3}{2}}]}{{(x^{3} - 5 x)}^{3}}$

Step 3.3.3

Since $3$ is constant with respect to $x$ , the derivative of $3 x^{4}$ with respect to $x$ is $3 \frac{d}{d x} [x^{4}]$ .

$\frac{1}{4 \cdot 5^{\frac{1}{2}}} \cdot \frac{{(x^{3} - 5 x)}^{\frac{3}{2}} (3 \frac{d}{d x} [x^{4}] + \frac{d}{d x} [- 30 x^{2}] + \frac{d}{d x} [- 25]) - (3 x^{4} - 30 x^{2} - 25) \frac{d}{d x} [{(x^{3} - 5 x)}^{\frac{3}{2}}]}{{(x^{3} - 5 x)}^{3}}$

$\frac{1}{4 \cdot 5^{\frac{1}{2}}} \cdot \frac{{(x^{3} - 5 x)}^{\frac{3}{2}} (12 x^{3} - 60 x + \frac{d}{d x} [- 25]) - (3 x^{4} - 30 x^{2} - 25) \frac{d}{d x} [{(x^{3} - 5 x)}^{\frac{3}{2}}]}{{(x^{3} - 5 x)}^{3}}$

Step 3.3.9

Since $- 25$ is constant with respect to $x$ , the derivative of $- 25$ with respect to $x$ is $0$ .

$\frac{1}{4 \cdot 5^{\frac{1}{2}}} \cdot \frac{{(x^{3} - 5 x)}^{\frac{3}{2}} (12 x^{3} - 60 x + 0) - (3 x^{4} - 30 x^{2} - 25) \frac{d}{d x} [{(x^{3} - 5 x)}^{\frac{3}{2}}]}{{(x^{3} - 5 x)}^{3}}$

Step 3.3.10

Add $12 x^{3} - 60 x$ and $0$ .

$\frac{1}{4 \cdot 5^{\frac{1}{2}}} \cdot \frac{{(x^{3} - 5 x)}^{\frac{3}{2}} (12 x^{3} - 60 x) - (3 x^{4} - 30 x^{2} - 25) \frac{d}{d x} [{(x^{3} - 5 x)}^{\frac{3}{2}}]}{{(x^{3} - 5 x)}^{3}}$

Step 3.4

Differentiate using the chain rule, which states that $\frac{d}{d x} [f (g (x))]$ is $f' (g (x)) g' (x)$ where $f (x) = x^{\frac{3}{2}}$ and $g (x) = x^{3} - 5 x$ .

Step 3.5

To write $- 1$ as a fraction with a common denominator, multiply by $\frac{2}{2}$ .

$\frac{1}{4 \cdot 5^{\frac{1}{2}}} \cdot \frac{{(x^{3} - 5 x)}^{\frac{3}{2}} (12 x^{3} - 60 x) - (3 x^{4} - 30 x^{2} - 25) (\frac{3}{2} {(x^{3} - 5 x)}^{\frac{3}{2} - 1 \cdot \frac{2}{2}} \frac{d}{d x} [x^{3} - 5 x])}{{(x^{3} - 5 x)}^{3}}$
