x  - 4*x
x34xx^{3} - 4 x
x^3 - 4*x
Detail solution
  1. Differentiate x34xx^{3} - 4 x term by term:

    1. Apply the power rule: x3x^{3} goes to 3x23 x^{2}

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

      1. Apply the power rule: xx goes to 11

      So, the result is: 4-4

    The result is: 3x243 x^{2} - 4


The answer is:

3x243 x^{2} - 4
