The solution

You have entered [src]

 2      
x  + 4*x

$$x^{2} + 4 x$$

x^2 + 4*x

Detail solution

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: $2 x + 4$

The answer is:

$2 x + 4$
