-x^4 + 2*x^2 + 3
Detail solution
  1. Differentiate (x4+2x2)+3\left(- x^{4} + 2 x^{2}\right) + 3 term by term:

    1. Differentiate x4+2x2- x^{4} + 2 x^{2} term by term:

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

        1. Apply the power rule: x4x^{4} goes to 4x34 x^{3}

        So, the result is: 4x3- 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: x2x^{2} goes to 2x2 x

        So, the result is: 4x4 x

      The result is: 4x3+4x- 4 x^{3} + 4 x

    2. The derivative of the constant 33 is zero.

    The result is: 4x3+4x- 4 x^{3} + 4 x

  2. Now simplify:

    4x(1x2)4 x \left(1 - x^{2}\right)


The answer is:

4x(1x2)4 x \left(1 - x^{2}\right)
