x  - 2*x 
$$x^{4} - 2 x^{2}$$
x^4 - 2*x^2
Detail solution
  1. Differentiate term by term:

    1. Apply the power rule: goes to

    2. The derivative of a constant times a function is the constant times the derivative of the function.

      1. Apply the power rule: goes to

      So, the result is:

    The result is:

  2. Now simplify:


The answer is:

The graph
The first derivative [src]
          3
-4*x + 4*x 
$$4 x^{3} - 4 x$$
The second derivative [src]
  /        2\
4*\-1 + 3*x /
$$4 \left(3 x^{2} - 1\right)$$
The third derivative [src]
24*x
$$24 x$$
