Derivative of x^4-2x^2

The solution

You have entered [src]

 4      2
x  - 2*x

$$x^{4} - 2 x^{2}$$

x^4 - 2*x^2

Detail solution

Differentiate $x^{4} - 2 x^{2}$ term by term:
1. Apply the power rule: $x^{4}$ goes to $4 x^{3}$
2. 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: $- 4 x$
The result is: $4 x^{3} - 4 x$
Now simplify:

$4 x \left(x^{2} - 1\right)$

The answer is:

$4 x \left(x^{2} - 1\right)$
