Detail solution

Differentiate $- 4 x^{2} - 2 x + 3$ term by term:
1. The derivative of the constant $3$ is zero.
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: $2$
  So, the result is: $-2$
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: $x^{2}$ goes to $2 x$
    So, the result is: $8 x$
  So, the result is: $- 8 x$
The result is: $- 8 x - 2$

The answer is:

$- 8 x - 2$
