Derivative of x^2-4*x-5

The solution

You have entered [src]

 2          
x  - 4*x - 5

$$\left(x^{2} - 4 x\right) - 5$$

x^2 - 4*x - 5

Detail solution

Differentiate $\left(x^{2} - 4 x\right) - 5$ term by term:
1. Differentiate $x^{2} - 4 x$ 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. Apply the power rule: $x$ goes to $1$
    So, the result is: $-4$
  The result is: $2 x - 4$
2. The derivative of the constant $-5$ is zero.
The result is: $2 x - 4$

The answer is:

$2 x - 4$
