(x^2 - 1)^2
Detail solution
  1. Let u=x21u = x^{2} - 1.

  2. Apply the power rule: u2u^{2} goes to 2u2 u

  3. Then, apply the chain rule. Multiply by ddx(x21)\frac{d}{d x} \left(x^{2} - 1\right):

    1. Differentiate x21x^{2} - 1 term by term:

      1. Apply the power rule: x2x^{2} goes to 2x2 x

      2. The derivative of the constant 1-1 is zero.

      The result is: 2x2 x

    The result of the chain rule is:

    2x(2x22)2 x \left(2 x^{2} - 2\right)

  4. Now simplify:

    4x(x21)4 x \left(x^{2} - 1\right)


The answer is:

4x(x21)4 x \left(x^{2} - 1\right)
