Detail solution

Differentiate $x^{3} - 6 x^{2} - 9 x$ term by term:
1. Apply the power rule: $x^{3}$ goes to $3 x^{2}$
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: $x^{2}$ goes to $2 x$
    So, the result is: $12 x$
  So, the result is: $- 12 x$
3. 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: $9$
  So, the result is: $-9$
The result is: $3 x^{2} - 12 x - 9$

The answer is:

$3 x^{2} - 12 x - 9$
