Step 2.7.1

To apply the Chain Rule, set $u_{2}$ as $x + 1$ .

$f'' (x) = - \frac{{(x + 1)}^{2} {(x + 3)}^{2} (2 x - 8) - (x^{2} - 8 x - 19) (2 {(x + 1)}^{2} (x + 3) + {(x + 3)}^{2} (\frac{d}{d u (2)} ({u_{2}}^{2}) \frac{d}{d x} (x + 1)))}{{({(x + 1)}^{2} {(x + 3)}^{2})}^{2}} + \frac{x^{2} - 8 x - 19}{{(x + 1)}^{2} {(x + 3)}^{2}} \cdot \frac{d}{d x} (- 1)$

Step 2.7.2

Differentiate using the Power Rule which states that $\frac{d}{d u_{2}} [{u_{2}}^{n}]$ is $n {u_{2}}^{n - 1}$ where $n = 2$ .

$f'' (x) = - \frac{{(x + 1)}^{2} {(x + 3)}^{2} (2 x - 8) - (x^{2} - 8 x - 19) (2 {(x + 1)}^{2} (x + 3) + {(x + 3)}^{2} (2 u_{2} \frac{d}{d x} (x + 1)))}{{({(x + 1)}^{2} {(x + 3)}^{2})}^{2}} + \frac{x^{2} - 8 x - 19}{{(x + 1)}^{2} {(x + 3)}^{2}} \cdot \frac{d}{d x} (- 1)$

Step 2.7.3

Replace all occurrences of $u_{2}$ with $x + 1$ .

$f'' (x) = - \frac{{(x + 1)}^{2} {(x + 3)}^{2} (2 x - 8) - (x^{2} - 8 x - 19) (2 {(x + 1)}^{2} (x + 3) + {(x + 3)}^{2} (2 (x + 1) \frac{d}{d x} (x + 1)))}{{({(x + 1)}^{2} {(x + 3)}^{2})}^{2}} + \frac{x^{2} - 8 x - 19}{{(x + 1)}^{2} {(x + 3)}^{2}} \cdot \frac{d}{d x} (- 1)$

Step 2.8.1

Move $2$ to the left of ${(x + 3)}^{2}$ .

$f'' (x) = - \frac{{(x + 1)}^{2} {(x + 3)}^{2} (2 x - 8) - (x^{2} - 8 x - 19) (2 {(x + 1)}^{2} (x + 3) + 2 \cdot ({(x + 3)}^{2} (x + 1)) \frac{d}{d x} (x + 1))}{{({(x + 1)}^{2} {(x + 3)}^{2})}^{2}} + \frac{x^{2} - 8 x - 19}{{(x + 1)}^{2} {(x + 3)}^{2}} \cdot \frac{d}{d x} (- 1)$

Step 2.8.2

By the Sum Rule, the derivative of $x + 1$ with respect to $x$ is $\frac{d}{d x} [x] + \frac{d}{d x} [1]$ .

$f'' (x) = - \frac{{(x + 1)}^{2} {(x + 3)}^{2} (2 x - 8) - (x^{2} - 8 x - 19) (2 {(x + 1)}^{2} (x + 3) + 2 {(x + 3)}^{2} (x + 1) (\frac{d}{d x} (x) + \frac{d}{d x} (1)))}{{({(x + 1)}^{2} {(x + 3)}^{2})}^{2}} + \frac{x^{2} - 8 x - 19}{{(x + 1)}^{2} {(x + 3)}^{2}} \cdot \frac{d}{d x} (- 1)$

Step 2.8.3

Differentiate using the Power Rule which states that $\frac{d}{d x} [x^{n}]$ is $n x^{n - 1}$ where $n = 1$ .

$f'' (x) = - \frac{{(x + 1)}^{2} {(x + 3)}^{2} (2 x - 8) - (x^{2} - 8 x - 19) (2 {(x + 1)}^{2} (x + 3) + 2 {(x + 3)}^{2} (x + 1) (1 + \frac{d}{d x} (1)))}{{({(x + 1)}^{2} {(x + 3)}^{2})}^{2}} + \frac{x^{2} - 8 x - 19}{{(x + 1)}^{2} {(x + 3)}^{2}} \cdot \frac{d}{d x} (- 1)$

Step 2.8.4

Since $1$ is constant with respect to $x$ , the derivative of $1$ with respect to $x$ is $0$ .

$f'' (x) = - \frac{{(x + 1)}^{2} {(x + 3)}^{2} (2 x - 8) - (x^{2} - 8 x - 19) (2 {(x + 1)}^{2} (x + 3) + 2 {(x + 3)}^{2} (x + 1) (1 + 0))}{{({(x + 1)}^{2} {(x + 3)}^{2})}^{2}} + \frac{x^{2} - 8 x - 19}{{(x + 1)}^{2} {(x + 3)}^{2}} \cdot \frac{d}{d x} (- 1)$

Step 4.1.2.2

Differentiate using the Power Rule which states that $\frac{d}{d x} [x^{n}]$ is $n x^{n - 1}$ where $n = 1$ .

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