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

    1. Let u=2x1u = 2 x - 1.

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

    3. Then, apply the chain rule. Multiply by ddx(2x1)\frac{d}{d x} \left(2 x - 1\right):

      1. Differentiate 2x12 x - 1 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: xx goes to 11

          So, the result is: 22

        2. The derivative of the constant (1)1\left(-1\right) 1 is zero.

        The result is: 22

      The result of the chain rule is:

      8x48 x - 4

    So, the result is: 24x1224 x - 12


The answer is:

24x1224 x - 12
