Detail solution

Differentiate $x^{2} - 5 x + 4$ 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. 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: $5$
  So, the result is: $-5$
3. The derivative of the constant $4$ is zero.
The result is: $2 x - 5$

The answer is:

$2 x - 5$
