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)=x−3f{\left(x \right)} = x - 3 and g(x)=x+4g{\left(x \right)} = x + 4.

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

    1. Differentiate x−3x - 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

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

    1. Differentiate x+4x + 4 term by term:

      1. The derivative of the constant 44 is zero.

      2. Apply the power rule: xx goes to 11

      The result is: 11

    Now plug in to the quotient rule:

    7(x+4)2\frac{7}{\left(x + 4\right)^{2}}

The answer is:

7(x+4)2\frac{7}{\left(x + 4\right)^{2}}
