Derivative of (x+7)^2

The solution

You have entered [src]

       2
(x + 7)

$$\left(x + 7\right)^{2}$$

(x + 7)^2

Detail solution

Let $u = x + 7$ .
Apply the power rule: $u^{2}$ goes to $2 u$
Then, apply the chain rule. Multiply by $\frac{d}{d x} \left(x + 7\right)$ :
1. Differentiate $x + 7$ term by term:
  1. Apply the power rule: $x$ goes to $1$
  2. The derivative of the constant $7$ is zero.
  The result is: $1$
The result of the chain rule is:

$2 x + 14$

The answer is:

$2 x + 14$
