Detail solution
  1. Differentiate 4x22x+3- 4 x^{2} - 2 x + 3 term by term:

    1. The derivative of the constant 33 is zero.

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

      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

      So, the result is: 2-2

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

      1. 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: 8x8 x

      So, the result is: 8x- 8 x

    The result is: 8x2- 8 x - 2


The answer is:

8x2- 8 x - 2
