The solution

You have entered [src]

   2          
2*x  - 3*x - 1

$$\left(2 x^{2} - 3 x\right) - 1$$

2*x^2 - 3*x - 1

Detail solution

Differentiate $\left(2 x^{2} - 3 x\right) - 1$ term by term:
1. Differentiate $2 x^{2} - 3 x$ 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: $4 x$
  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: $-3$
  The result is: $4 x - 3$
2. The derivative of the constant $-1$ is zero.
The result is: $4 x - 3$

The answer is:

$4 x - 3$
