Detail solution
  1. Apply the quotient rule, which is:

    ddxf(x)g(x)=f(x)ddxg(x)+g(x)ddxf(x)g2(x)\frac{d}{d x} \frac{f{\left(x \right)}}{g{\left(x \right)}} = \frac{- f{\left(x \right)} \frac{d}{d x} g{\left(x \right)} + g{\left(x \right)} \frac{d}{d x} f{\left(x \right)}}{g^{2}{\left(x \right)}}

    f(x)=2x+2f{\left(x \right)} = 2 x + 2 and g(x)=x3g{\left(x \right)} = x - 3.

    To find ddxf(x)\frac{d}{d x} f{\left(x \right)}:

    1. Differentiate 2x+22 x + 2 term by term:

      1. The derivative of the constant 22 is zero.

      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: 22

      The result is: 22

    To find ddxg(x)\frac{d}{d x} g{\left(x \right)}:

    1. Differentiate x3x - 3 term by term:

      1. The derivative of the constant 3-3 is zero.

      2. Apply the power rule: xx goes to 11

      The result is: 11

    Now plug in to the quotient rule:

    8(x3)2- \frac{8}{\left(x - 3\right)^{2}}


The answer is:

8(x3)2- \frac{8}{\left(x - 3\right)^{2}}
