Derivative of x^3+3x^2-9x

The solution

You have entered [src]

 3      2      
x  + 3*x  - 9*x

$$- 9 x + \left(x^{3} + 3 x^{2}\right)$$

x^3 + 3*x^2 - 9*x

Detail solution

Differentiate $- 9 x + \left(x^{3} + 3 x^{2}\right)$ term by term:
1. Differentiate $x^{3} + 3 x^{2}$ 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. Apply the power rule: $x^{2}$ goes to $2 x$
    So, the result is: $6 x$
  The result is: $3 x^{2} + 6 x$
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: $-9$
The result is: $3 x^{2} + 6 x - 9$

The answer is:

$3 x^{2} + 6 x - 9$
