Transform

Detail solution

Let $u = x^{2} - 12 x + 56$ .
Apply the power rule: $\sqrt{u}$ goes to $\frac{1}{2 \sqrt{u}}$
Then, apply the chain rule. Multiply by $\frac{d}{d x} \left(x^{2} - 12 x + 56\right)$ :
1. Differentiate $x^{2} - 12 x + 56$ term by term:
  1. Apply the power rule: $x^{2}$ goes to $2 x$
  2. The derivative of a constant times a function is the constant times the derivative of the function.
    1. 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: $12$
    So, the result is: $-12$
  3. The derivative of the constant $56$ is zero.
  The result is: $2 x - 12$
The result of the chain rule is:

$\frac{2 x - 12}{2 \sqrt{x^{2} - 12 x + 56}}$
Now simplify:

$\frac{x - 6}{\sqrt{x^{2} - 12 x + 56}}$

The answer is:

$\frac{x - 6}{\sqrt{x^{2} - 12 x + 56}}$
