Detail solution
  1. Apply the product rule:

    ddxf(x)g(x)=f(x)ddxg(x)+g(x)ddxf(x)\frac{d}{d x} f{\left(x \right)} g{\left(x \right)} = f{\left(x \right)} \frac{d}{d x} g{\left(x \right)} + g{\left(x \right)} \frac{d}{d x} f{\left(x \right)}

    f(x)=(x2)3f{\left(x \right)} = \left(x - 2\right)^{3}; to find ddxf(x)\frac{d}{d x} f{\left(x \right)}:

    1. Let u=x2u = x - 2.

    2. Apply the power rule: u3u^{3} goes to 3u23 u^{2}

    3. Then, apply the chain rule. Multiply by ddx(x2)\frac{d}{d x} \left(x - 2\right):

      1. Differentiate x2x - 2 term by term:

        1. Apply the power rule: xx goes to 11

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

        The result is: 11

      The result of the chain rule is:

      3(x2)23 \left(x - 2\right)^{2}

    g(x)=sin(2x)g{\left(x \right)} = \sin{\left(2 x \right)}; to find ddxg(x)\frac{d}{d x} g{\left(x \right)}:

    1. Let u=2xu = 2 x.

    2. The derivative of sine is cosine:

      ddusin(u)=cos(u)\frac{d}{d u} \sin{\left(u \right)} = \cos{\left(u \right)}

    3. Then, apply the chain rule. Multiply by ddx2x\frac{d}{d x} 2 x:

      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

      The result of the chain rule is:

      2cos(2x)2 \cos{\left(2 x \right)}

    The result is: 2(x2)3cos(2x)+3(x2)2sin(2x)2 \left(x - 2\right)^{3} \cos{\left(2 x \right)} + 3 \left(x - 2\right)^{2} \sin{\left(2 x \right)}

  2. Now simplify:

    (x2)2((2x4)cos(2x)+3sin(2x))\left(x - 2\right)^{2} \left(\left(2 x - 4\right) \cos{\left(2 x \right)} + 3 \sin{\left(2 x \right)}\right)


The answer is:

(x2)2((2x4)cos(2x)+3sin(2x))\left(x - 2\right)^{2} \left(\left(2 x - 4\right) \cos{\left(2 x \right)} + 3 \sin{\left(2 x \right)}\right)
