Transform

Detail solution

Let $u = 14 x^{2} + 16 x + 23$ .
Apply the power rule: $\sqrt{u}$ goes to $\frac{1}{2 \sqrt{u}}$
Then, apply the chain rule. Multiply by $\frac{d}{d x} \left(14 x^{2} + 16 x + 23\right)$ :
1. Differentiate $14 x^{2} + 16 x + 23$ term by term:
  1. The derivative of a constant times a function is the constant times the derivative of the function.
    1. Apply the power rule: $x^{2}$ goes to $2 x$
    So, the result is: $28 x$
  2. The derivative of a constant times a function is the constant times the derivative of the function.
    1. Apply the power rule: $x$ goes to $1$
    So, the result is: $16$
  3. The derivative of the constant $23$ is zero.
  The result is: $28 x + 16$
The result of the chain rule is:

$\frac{28 x + 16}{2 \sqrt{14 x^{2} + 16 x + 23}}$
Now simplify:

$\frac{2 \cdot \left(7 x + 4\right)}{\sqrt{14 x^{2} + 16 x + 23}}$

The answer is:

$\frac{2 \cdot \left(7 x + 4\right)}{\sqrt{14 x^{2} + 16 x + 23}}$
