x34x2x^{3} - 4 x^{2}
Detail solution
  1. Differentiate x34x2x^{3} - 4 x^{2} 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: x2x^{2} goes to 2x2 x

      So, the result is: 8x- 8 x

    The result is: 3x28x3 x^{2} - 8 x

  2. Now simplify:

    x(3x8)x \left(3 x - 8\right)


The answer is:

x(3x8)x \left(3 x - 8\right)
