${(x - 2)}^{3} {(x + 1)}^{4}$

Step 1

Differentiate using the Product Rule which states that $\frac{d}{d x} [f (x) g (x)]$ is $f (x) \frac{d}{d x} [g (x)] + g (x) \frac{d}{d x} [f (x)]$ where $f (x) = {(x - 2)}^{3}$ and $g (x) = {(x + 1)}^{4}$ .

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

Step 2

Differentiate using the chain rule, which states that $\frac{d}{d x} [f (g (x))]$ is $f' (g (x)) g' (x)$ where $f (x) = x^{4}$ and $g (x) = x + 1$ .

Step 2.1

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

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

Step 2.2

Differentiate using the Power Rule which states that $\frac{d}{d u_{1}} [{u_{1}}^{n}]$ is $n {u_{1}}^{n - 1}$ where $n = 4$ .

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

Step 2.3

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

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

Step 3.1

Move $4$ to the left of ${(x - 2)}^{3}$ .

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

Step 3.2

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

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

Step 3.3

Step 3.4

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

$4 {(x - 2)}^{3} {(x + 1)}^{3} (1 + 0) + {(x + 1)}^{4} \frac{d}{d x} [{(x - 2)}^{3}]$
